31 Mar '15

Arch Linux Security Advisory ASA-201503-26 ========================================== Severity: Critical Date : 2015-03-31 CVE-ID : CVE-2015-1817 Package : musl Type : arbitrary code execution Remote : No Link : https://wiki.archlinux.org/index.php/CVE Summary ======= The package musl before version 1.1.8-1 is vulnerable to arbitrary code execution. Resolution ========== Upgrade to 1.1.8-1. # pacman -Syu "musl>=1.1.8-1" The problem has been fixed upstream in version 1.1.8. Workaround ========== None. Description =========== A stack-based buffer overflow has been found in musl libc's ipv6 address literal parsing code. Programs which call the inet_pton or getaddrinfo function with AF_INET6 or AF_UNSPEC and untrusted address strings are affected. Successful exploitation yields control of the return address. Having enabled stack protector at the application level does not mitigate the issue. Impact ====== An attacker can execute arbitrary code by submitting a carefully crafted IPv6 address to a program linked with musl calling inet_pton() or getaddrinfo() with AF_INET6 or AF_UNSPEC.

Arch Linux Security Advisory ASA-201503-23 ========================================== Severity: Medium Date : 2015-03-24 CVE-ID : CVE-2014-9114 Package : util-linux Type : command injection Remote : No Link : https://wiki.archlinux.org/index.php/CVE Summary ======= The package util-linux before version 2.26.1-3 is vulnerable to command injection via malicious devices. Resolution ========== Upgrade to 2.26.1-3. # pacman -Syu "util-linux>=2.26.1-3" The problem has been fixed upstream in version 2.26. Workaround ========== None. Description =========== There is a command injection inside blkid. It uses caching files (/dev/.blkid.tab or /run/blkid/blkid.tab) to store info about the UUID, LABEL etc it finds on certain devices. However, it does not strip " character, so it can be confused to build variable names containing embedded shell metas, which it would usually encode inside the value. Impact ====== An attacker is able to use a specially prepared device with a malicious label to potentially inject arbitrary shell commands when mounted with a wrapper that uses 'blkid -o' passed to eval. References ========== http://seclists.org/oss-sec/2014/q4/811 https://access.redhat.com/security/cve/CVE-2014-9114 https://bugs.archlinux.org/task/43886

Resolution ========== Upgrade to 4.7.3-1. # pacman -Syu "tcpdump>=4.7.3-1" The problems have been fixed upstream in version 4.7.3. Workaround ========== None. Description =========== - CVE-2014-8767 (denial of service) Integer underflow in the olsr_print function when in verbose mode, allows remote attackers to cause a denial of service (crash) via a crafted length value in an OLSR frame. - CVE-2014-8768 (denial of service) Multiple Integer underflows in the geonet_print function, when in verbose mode, allow remote attackers to cause a denial of service (segmentation fault and crash) via a crafted length value in a Geonet frame. - CVE-2014-8769 (out-of-bounds memory read) Might allow remote attackers to obtain sensitive information from memory or cause a denial of service (packet loss or segmentation fault) via a crafted Ad hoc On-Demand Distance Vector (AODV) packet, which triggers an out-of-bounds memory access. - CVE-2014-9140 (denial of service) Buffer overflow in the ppp_hdlc function in print-ppp.c allows remote attackers to cause a denial of service (crash) cia a crafted PPP packet or possibly execute arbitrary code. - CVE-2015-0261 (out-of-bounds memory read) IPv6 mobility printer mobility_opt_print() typecastimg/signedness error would handle "len" as "int" (=positive and negative numbers), instead of "unsigned int" (=only positive numbers). When calling mobility_opt_print() with a negative "len", the "i < len" check would not be satisfied and it would not enter the loop and try to read from bp[i]. - CVE-2015-2153 (arbitrary code execution) TCP printer problem with missing length check in the rpki_rtr_pdu_print() function in print-rpki-rtr.c when processing RPKI-RTR PDUs (Protocol Data Units) with an incorrect header length. Without this check, the function will try to operate on invalid data when processing certain packets, leading to all kinds of unwanted side effects, including crashes due to invalid reads, writes and general memory corruption. Due to the memory corruption aspect it may lead to code execution. - CVE-2015-2154 (out-of-bounds memory read) Ethernet printer osi_print_cksum() missing sanity checks in print-isoclns.c. The function may call the create_osi_cksum() function in checksum.c with invalid data leading to out-of-bounds memory read. - CVE-2015-2155 (arbitrary code execution) A flaw was found in tcpdump's force printer.

Arch Linux Security Advisory ASA-201503-18 ========================================== Severity: Medium Date : 2015-03-20 CVE-ID : CVE-2015-2559 Package : drupal Type : multiple issues Remote : Yes Link : https://wiki.archlinux.org/index.php/CVE Summary ======= The package drupal before version 7.35-1 is vulnerable to access bypass and open redirects. Resolution ========== Upgrade to 7.35-1. # pacman -Syu "drupal>=7.35-1" The problems have been fixed upstream in version 7.35. Workaround ========== None. Description =========== - CVE-2015-2559 (access bypass) Password reset URLs can be forged under certain circumstances, allowing an attacker to gain access to another user's account without knowing the account's password. In Drupal 7, this vulnerability is mitigated by the fact that it can only be exploited on sites where accounts have been imported or programmatically edited in a way that results in the password hash in the database being the same for multiple user accounts. - None (open redirect) Under certain circumstances, malicious users can use the destination URL parameter to construct a URL that will trick users into being redirected to a 3rd party website, thereby exposing the users to potential social engineering attacks. Impact ====== A remote attacker may gain access to another user's account or take advantage of open redirect issues to trick users into being redirected to a 3rd party website.

19 Mar '15

Arch Linux Security Advisory ASA-201503-17 ========================================== Severity: High Date : 2015-03-19 CVE-ID : CVE-2015-1787 CVE-2015-0207 CVE-2015-0208 CVE-2015-0209 CVE-2015-0285 CVE-2015-0286 CVE-2015-0287 CVE-2015-0288 CVE-2015-0289 CVE-2015-0290 CVE-2015-0291 CVE-2015-0293 Package : lib32-openssl Type : multiple issues Remote : Yes Link : https://wiki.archlinux.org/index.php/CVE Summary ======= The package lib32-openssl before version 1.0.2.a-1 is vulnerable to multiple issues including but not limited to denial of service, unseeded PRNG and memory corruption. Resolution ========== Upgrade to 1.0.2.a-1. # pacman -Syu "lib32-openssl>=1.0.2.a-1" The problems have been fixed upstream in version 1.0.2.a. Workaround ========== None. Description =========== - CVE-2015-1787 (denial of service) If client auth is used then a server can segfault in the event of a DHE ciphersuite being selected and a zero length ClientKeyExchange message being sent by the client. This could be exploited in a DoS attack. - CVE-2015-0207 (denial of service) The DTLSv1_listen function is intended to be stateless and processes the initial ClientHello from many peers. It is common for user code to loop over the call to DTLSv1_listen until a valid ClientHello is received with an associated cookie. A defect in the implementation of DTLSv1_listen means that state is preserved in the SSL object from one invocation to the next that can lead to a segmentation fault. Errors processing the initial ClientHello can trigger this scenario. An example of such an error could be that a DTLS1.0 only client is attempting to connect to a DTLS1.2 only server. - CVE-2015-0208 (denial of service) The signature verification routines will crash with a NULL pointer dereference if presented with an ASN.1 signature using the RSA PSS algorithm and invalid parameters. Since these routines are used to verify certificate signature algorithms this can be used to crash any certificate verification operation and exploited in a DoS attack. Any application which performs certificate verification is vulnerable including OpenSSL clients and servers which enable client authentication. - CVE-2015-0209 (denial of service) A malformed EC private key file consumed via the d2i_ECPrivateKey function could cause a use after free condition. This, in turn, could cause a double free in several private key parsing functions (such as d2i_PrivateKey or EVP_PKCS82PKEY) and could lead to a DoS attack or memory corruption for applications that receive EC private keys from untrusted sources. This scenario is considered rare. - CVE-2015-0285 (unseeded PRNG) Under certain conditions an OpenSSL 1.0.2 client can complete a handshake with an unseeded PRNG. The conditions are: - The client is on a platform where the PRNG has not been seeded automatically, and the user has not seeded manually - A protocol specific client method version has been used (i.e. not SSL_client_methodv23) - A ciphersuite is used that does not require additional random data from the PRNG beyond the initial ClientHello client random (e.g. PSK-RC4-SHA). If the handshake succeeds then the client random that has been used will have been generated from a PRNG with insufficient entropy and therefore the output may be predictable. - CVE-2015-0286 (denial of service) The function ASN1_TYPE_cmp will crash with an invalid read if an attempt is made to compare ASN.1 boolean types. Since ASN1_TYPE_cmp is used to check certificate signature algorithm consistency this can be used to crash any certificate verification operation and exploited in a DoS attack. Any application which performs certificate verification is vulnerable including OpenSSL clients and servers which enable client authentication. - CVE-2015-0287 (memory corruption) Reusing a structure in ASN.1 parsing may allow an attacker to cause memory corruption via an invalid write. Such reuse is and has bee strongly discouraged and is believed to be rare. Applications that parse structures containing CHOICE or ANY DEFINED BY components may be affected. Certificate parsing (d2i_X509 and related functions) are however not affected. OpenSSL clients and servers are not affected. - CVE-2015-0288 (denial of service) The function X509_to_X509_REQ will crash with a NULL pointer dereference if the certificate key is invalid. This function is rarely used in practice. - CVE-2015-0289 (denial of service) The PKCS#7 parsing code does not handle missing outer ContentInfo correctly. An attacker can craft malformed ASN.1-encoded PKCS#7 blobs with missing content and trigger a NULL pointer dereference on parsing. Applications that verify PKCS#7 signatures, decrypt PKCS#7 data or otherwise parse PKCS#7 structures from untrusted sources are affected. OpenSSL clients and servers are not affected. - CVE-2015-0290 (denial of service) OpenSSL 1.0.2 introduced the "multiblock" performance improvement. This feature only applies on 64 bit x86 architecture platforms that support AES NI instructions. A defect in the implementation of "multiblock" can cause OpenSSL's internal write buffer to become incorrectly set to NULL when using non-blocking IO. Typically, when the user application is using a socket BIO for writing, this will only result in a failed connection. However if some other BIO is used then it is likely that a segmentation fault will be triggered, thus enabling a potential DoS attack. - CVE-2015-0291 (denial of service) If a client connects to an OpenSSL 1.0.2 server and renegotiates via ClientHello with an invalid signature algorithms extension a NULL pointer dereference will occur. This can be exploited in a DoS attack against the server. - CVE-2015-0293 (denial of service) A malicious client can trigger an OPENSSL_assert (i.e., an abort) in servers that both support SSLv2 and enable export cipher suites by sending a specially crafted SSLv2 CLIENT-MASTER-KEY message. Impact ====== A remote attacker is able to perform denial of service, memory corruption or possibly take advantage of an unseeded PRNG via various vectors.

However if some other BIO is used then it is likely that a segmentation fault will be triggered, thus enabling a potential DoS attack. - CVE-2015-0291 (denial of service) If a client connects to an OpenSSL 1.0.2 server and renegotiates via ClientHello with an invalid signature algorithms extension a NULL pointer dereference will occur. This can be exploited in a DoS attack against the server. - CVE-2015-0293 (denial of service) A malicious client can trigger an OPENSSL_assert (i.e., an abort) in servers that both support SSLv2 and enable export cipher suites by sending a specially crafted SSLv2 CLIENT-MASTER-KEY message. Impact ====== A remote attacker is able to perform denial of service, memory corruption or possibly take advantage of an unseeded PRNG via various vectors.

[arch-security] [ASA-201503-15] libxfont: multiple issues
by Levente Polyak 17 Mar '15

17 Mar '15

Arch Linux Security Advisory ASA-201503-15 ========================================== Severity: Critical Date : 2015-03-17 CVE-ID : CVE-2015-1802 CVE-2015-1803 CVE-2015-1804 Package : libxfont Type : multiple issues Remote : No Link : https://wiki.archlinux.org/index.php/CVE Summary ======= The package libxfont before version 1.5.1-1 is vulnerable to multiple issues including denial of service and out-of-bounds memory read/write leading to arbitrary code execution with the privileges of the X server. Resolution ========== Upgrade to 1.5.1-1. # pacman -Syu "libxfont>=1.5.1-1" The problem has been fixed upstream in version 1.5.1. Workaround ========== None. Description =========== As libXfont is used by the X server to read font files, and an unprivileged user with access to the X server can tell the X server to read a given font file from a path of their choosing, these vulnerabilities have the potential to allow unprivileged users to run code with the privileges of the X server (often root access). - CVE-2015-1802 (out-of-bounds memory write) The bdf parser reads a count for the number of properties defined in a font from the font file, and allocates arrays with entries for each property based on that count. It never checked to see if that count was negative, or large enough to overflow when multiplied by the size of the structures being allocated, and could thus allocate the wrong buffer size, leading to out of bounds writes. - CVE-2015-1803 (denial of service) If the bdf parser failed to parse the data for the bitmap for any character, it would proceed with an invalid pointer to the bitmap data and later crash when trying to read the bitmap from that pointer. - CVE-2015-1804 (out-of-bounds memory read) The bdf parser read metrics values as 32-bit integers, but stored them into 16-bit integers. Overflows could occur in various operations leading to out-of-bounds memory access. Impact ====== A local attacker is able to use specially crafted font files to perform denial of service or execute arbitrary code with the privileges of the X server resulting in local privilege escalation.

[arch-security] [ASA-201503-14] ecryptfs-utils: hard-coded passphrase salt
by Levente Polyak 17 Mar '15

17 Mar '15

Arch Linux Security Advisory ASA-201503-14 ========================================== Severity: Low Date : 2015-03-17 CVE-ID : CVE-2014-9687 Package : ecryptfs-utils Type : hard-coded passphrase salt Remote : No Link : https://wiki.archlinux.org/index.php/CVE Summary ======= The package ecryptfs-utils before version 106-1 is vulnerable to hard-coded passphrase salt that may ease a brute-force attack. Resolution ========== Upgrade to 106-1. # pacman -Syu "ecryptfs-utils>=106-1" The problem has been fixed upstream in version 106. If pam_ecryptfs is used a transparent migration from version 1 to version 2 files is provided, otherwise a manual re-wrapping of the passphrase file is mandatory. Workaround ========== None. Description =========== eCryptfs uses a default salt to encrypt the mount passphrase, which makes it easier for attackers to obtain user passwords via a brute force attack. By default, the wrapping key is hashed with the default fixed salt (0x0011223344556677). This update introduces the version 2 wrapped-passphrase file format. It adds the ability to combine a randomly generated salt with the wrapping password (typically, a user's login password) prior to performing key strengthening. The version 2 file format is considered to be a intermediate step in strengthening the wrapped-passphrase files of existing encrypted home/private users. If pam_ecryptfs is used a transparent migration from version 1 to version 2 files is provided, otherwise a manual re-wrapping of the passphrase file is mandatory. Impact ====== An attacker could use this issue to discover the login password used to protect the mount passphrase and gain unintended access to the encrypted files with the help of bulk dictionary attacks and rainbow tables to crack user passwords.

16 Mar '15

Arch Linux Security Advisory ASA-201503-10 ========================================== Severity: Medium Date : 2015-03-16 CVE-ID : CVE-2014-8242 Package : librsync Type : checksum collision Remote : Yes Link : https://wiki.archlinux.org/index.php/CVE Summary ======= The package librsync before version 1.0.0-1 is vulnerable to checksum collision leading to possible file modification or corruption via a birthday attack. Resolution ========== Upgrade to 1.0.0-1. # pacman -Syu "librsync>=1.0.0-1" The problem has been fixed upstream in version 1.0.0. Workaround ========== None. Description =========== librsync previously used a truncated MD4 "strong" check sum to match blocks. However, MD4 is not cryptographically strong. It's possible that an attacker who can control the contents of one part of a file could use it to control other regions of the file, if it's transferred using librsync/rdiff. For example this might occur in a database, mailbox, or VM image containing some attacker-controlled data. To mitigate this issue, signatures will by default be computed with a 256-bit BLAKE2 hash. Old versions of librsync will complain about a bad magic number when given these signature files. Impact ====== An attacker is able to take advantage of the weak checksum calculation by using a birthday attack in order to corrupt or modify files that are transfered.

Arch Linux Security Advisory ASA-201503-8 ========================================= Severity: Medium Date : 2015-03-12 CVE-ID : CVE-2015-1572 Package : e2fsprogs Type : arbitrary code execution Remote : No Link : https://wiki.archlinux.org/index.php/CVE Summary ======= The package e2fsprogs before version 1.42.12-2 is vulnerable to heap buffer overflow leading to arbitrary code execution. Resolution ========== Upgrade to 1.42.12-2. # pacman -Syu "e2fsprogs>=1.42.12-2" The problem has been fixed upstream but no release is available yet. Workaround ========== None. Description =========== If corrupted file system didn't trip over some corruption check, and then the file system was modified via tune2fs or debugfs, such that the superblock was marked dirty and then written out via the closefs() path, it's possible that the buffer overrun could be triggered when the file system is closed. This issue can lead to arbitrary code execution if a malicious device is plugged in and the mounting process chooses to run fsck (or other application using the ext2fs library) on the device's malicious filesystem. Impact ====== A local attacker is able to execute arbitrary code with a plugged in malicious device by causing a crafted block group descriptor to be marked as dirty and then accessed by an application using the ext2fs library like fsck.

[arch-security] [ASA-201503-4] grep: denial of service
by Levente Polyak 05 Mar '15

05 Mar '15

Arch Linux Security Advisory ASA-201503-4 ========================================= Severity: Low Date : 2015-03-05 CVE-ID : CVE-2015-1345 Package : grep Type : denial of service Remote : No Link : https://wiki.archlinux.org/index.php/CVE Summary ======= The package grep before version 2.21-2 is vulnerable to denial of service via heap buffer out-of-bounds read. Resolution ========== Upgrade to 2.21-2. # pacman -Syu "grep>=2.21-2" The problem has been fixed upstream but no release is available yet. Workaround ========== None. Description =========== The bmexec_trans function in kwset.c allows local users to cause a denial of service (out-of-bounds heap read and crash) via crafted input when using the -F option. grep's read buffer is often filled to its full size, except when reading the final buffer of a file. In that case, the number of bytes read may be far less than the size of the buffer. However, for certain unusual pattern/text combinations, grep -F would mistakenly examine bytes in that uninitialized region of memory when searching for a match. With carefully chosen inputs, one can cause grep -F to read beyond the end of that buffer altogether. This problem arose via commit v2.18-90-g73893ff with the introduction of a more efficient heuristic using what is now the memchr_kwset function. The use of that function in bmexec_trans could leave TP much larger than EP, and the subsequent call to bm_delta2_search would mistakenly access beyond end of the main input read buffer. Impact ====== A local attacker is able to use specially crafted input when using the -F option to cause a heap buffer out-of-bounds read leading to denial of service.

Arch Linux Security Advisory ASA-201503-3 ========================================= Severity: Medium Date : 2015-03-02 CVE-ID : CVE-2014-9447 Package : lib32-elfutils Type : directory traversal Remote : Yes Link : https://wiki.archlinux.org/index.php/CVE Summary ======= The package lib32-elfutils before version 0.161-2 is vulnerable to directory traversal. Resolution ========== Upgrade to 0.161-2. # pacman -Syu "lib32-elfutils>=0.161-2" The problem has been fixed upstream but no release is available yet. Workaround ========== None. Description =========== Directory traversal vulnerability in the read_long_names function in libelf/elf_begin.c allows remote attackers to write to arbitrary files to the root directory via a / (slash) in a crafted archive, as demonstrated using the ar program. Impact ====== A remote attacker is able to use a specially crafted archive to write to arbitrary files to the root directory.

[arch-security] [ASA-201503-1] putty: information disclosure

Arch Linux Security Advisory ASA-201503-1 ========================================= Severity: Medium Date : 2015-03-02 CVE-ID : CVE-2015-2157 Package : putty Type : information disclosure Remote : No Link : https://wiki.archlinux.org/index.php/CVE Summary ======= The package putty before version 0.64-1 is vulnerable to information disclosure of SSH-2 private key information. Resolution ========== Upgrade to 0.64-1. # pacman -Syu "putty>=0.64-1" The problem has been fixed upstream in version 0.64. Workaround ========== None. Description =========== When PuTTY has sensitive data in memory and has no further need for it, it should wipe the data out of its memory, in case malware later gains access to the PuTTY process or the memory is swapped out to disk or written into a crash dump file. An obvious example of this is the password typed during SSH login; other examples include obsolete session keys, public-key passphrases, and the private halves of public keys. After loading a private key from a disk file, PuTTY mistakenly leak a memory buffer containing a copy of the private key, in the function ssh2_load_userkey. The companion function ssh2_save_userkey (only called by PuTTYgen) can also leak a copy, but only in the case where the file it tried to save to could not be created. This applies to SSH-2 private keys only. It affects all tools in the PuTTY suite which load or save private keys: PuTTY, Plink, PSCP, PSFTP, Pageant and PuTTYgen. If any of those programs loads a private key directly (rather than getting a signature from an SSH agent such as Pageant) then they will have left information equivalent to the private key in memory for their entire run. Impact ====== A local attacker is able to retrieve SSH-2 private key information from memory after loading and saving key files to disk as a result of inappropriate wipe.
