Arch Linux Security Advisory ASA-201806-14 ========================================== Severity: Critical Date : 2018-06-27 CVE-ID : CVE-2018-5186 CVE-2018-5187 CVE-2018-5188 CVE-2018-12356 CVE-2018-12358 CVE-2018-12359 CVE-2018-12360 CVE-2018-12361 CVE-2018-12362 CVE-2018-12363 CVE-2018-12364 CVE-2018-12365 CVE-2018-12366 CVE-2018-12367 CVE-2018-12369 CVE-2018-12370 CVE-2018-12371 Package : firefox Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-727 Summary ======= The package firefox before version 61.0-1 is vulnerable to multiple issues including arbitrary code execution, cross-site request forgery, same-origin policy bypass, access restriction bypass and information disclosure. Resolution ========== Upgrade to 61.0-1. # pacman -Syu "firefox>=61.0-1" The problems have been fixed upstream in version 61.0. Workaround ========== None. Description =========== - CVE-2018-5186 (arbitrary code execution) Several memory safety bugs have been found in Firefox before 61.0. Some of these bugs showed evidence of memory corruption and Mozilla presumes that with enough effort some of these could be exploited to run arbitrary code. - CVE-2018-5187 (arbitrary code execution) Several memory safety bugs have been found in Firefox before 61.0. Some of these bugs showed evidence of memory corruption and Mozilla presumes that with enough effort some of these could be exploited to run arbitrary code. - CVE-2018-5188 (arbitrary code execution) Several memory safety bugs have been found in Firefox before 61.0. Some of these bugs showed evidence of memory corruption and Mozilla presumes that with enough effort some of these could be exploited to run arbitrary code. - CVE-2018-12356 (arbitrary code execution) An issue was discovered in password-store.sh in pass in Simple Password Store 1.7 through 1.7.1. The signature verification routine parses the output of GnuPG with an incomplete regular expression, which allows remote attackers to spoof file signatures on configuration files and extensions scripts. Modifying the configuration file allows the attacker to inject additional encryption keys under their control, thereby disclosing passwords to the attacker. Modifying the extension scripts allows the attacker arbitrary code execution. - CVE-2018-12358 (same-origin policy bypass) Service workers in Firefox before 61.0 can use redirection to avoid the tainting of cross-origin resources in some instances, allowing a malicious site to read responses which are supposed to be opaque. - CVE-2018-12359 (arbitrary code execution) A buffer overflow can occur in Firefox before 61.0 when rendering canvas content while adjusting the height and width of the <canvas> element dynamically, causing data to be written outside of the currently computed boundaries. This results in a potentially exploitable crash. - CVE-2018-12360 (arbitrary code execution) A use-after-free vulnerability can occur in Firefox before 61.0 when deleting an input element during a mutation event handler triggered by focusing that element. This results in a potentially exploitable crash. - CVE-2018-12361 (arbitrary code execution) An integer overflow can occur in Firefox before 61.0 in the SwizzleData code while calculating buffer sizes. The overflowed value is used for subsequent graphics computations when their inputs are not sanitized which results in a potentially exploitable crash. - CVE-2018-12362 (arbitrary code execution) An integer overflow can occur in Firefox before 61.0 during graphics operations done by the Supplemental Streaming SIMD Extensions 3 (SSSE3) scaler, resulting in a potentially exploitable crash. - CVE-2018-12363 (arbitrary code execution) A use-after-free vulnerability can occur in Firefox before 61.0 when script uses mutation events to move DOM nodes between documents, resulting in the old document that held the node being freed but the node still having a pointer referencing it. This results in a potentially exploitable crash. - CVE-2018-12364 (cross-site request forgery) A security issue has been found in Firefox before 61.0 where NPAPI plugins, such as Adobe Flash, can send non-simple cross-origin requests, bypassing CORS by making a same-origin POST that does a 307 redirect to the target site. This allows for a malicious site to engage in cross-site request forgery (CSRF) attacks. - CVE-2018-12365 (information disclosure) A security issue has been found in Firefox before 61.0 where a compromised IPC child process can escape the content sandbox and list the names of arbitrary files on the file system without user consent or interaction. This could result in exposure of private local files. - CVE-2018-12366 (information disclosure) An invalid grid size during QCMS (color profile) transformations can result in the out-of-bounds read interpreted as a float value, in Firefox before 61.0. This could leak private data into the output. - CVE-2018-12367 (information disclosure) A security issue has been found in Firefox before 61.0. In the previous mitigations for Spectre, the resolution or precision of various methods was reduced to counteract the ability to measure precise time intervals. In that work, PerformanceNavigationTiming was not adjusted but it was found that it could be used as a precision timer. - CVE-2018-12369 (access restriction bypass) WebExtensions bundled with embedded experiments were not correctly checked for proper authorization before Firefox 61.0. This allowed a malicious WebExtension to gain full browser permissions. - CVE-2018-12370 (access restriction bypass) In the Reader View of Firefox before 61.0, SameSite cookie protections are not checked on exiting. This allows for a payload to be triggered when Reader View is exited if loaded by a malicious site while Reader mode is active, bypassing CSRF protections. - CVE-2018-12371 (arbitrary code execution) An integer overflow vulnerability has been found in the Skia library shipped with Firefox before 61.0, when allocating memory for edge builders on some systems with at least 16 GB of RAM. This results in the use of uninitialized memory, resulting in a potentially exploitable crash. Impact ====== A remote attacker can access sensitive information, bypass various security mechanisms and execute arbitrary code on the affected host.

Arch Linux Security Advisory ASA-201806-12 ========================================== Severity: High Date : 2018-06-20 CVE-ID : CVE-2018-12559 CVE-2018-12560 CVE-2018-12561 CVE-2018-12562 Package : cantata Type : multiple issues Remote : No Link : https://security.archlinux.org/AVG-721 Summary ======= The package cantata before version 2.3.1-2 is vulnerable to multiple issues including access restriction bypass and privilege escalation. Resolution ========== Upgrade to 2.3.1-2. # pacman -Syu "cantata>=2.3.1-2" The problems have been fixed upstream but no release is available yet. Workaround ========== None. Description =========== - CVE-2018-12559 (privilege escalation) An issue was discovered in the cantata-mounter D-Bus service in Cantata through 2.3.1. The mount target path check in mounter.cpp `mpOk()` is insufficient. A regular user can consequently mount a CIFS filesystem anywhere (e.g., outside of the /home directory tree) by passing directory traversal sequences such as a home/../usr substring. - CVE-2018-12560 (access restriction bypass) An issue was discovered in the cantata-mounter D-Bus service in Cantata through 2.3.1. Arbitrary unmounts can be performed by regular users via directory traversal sequences such as a home/../sys/kernel substring. - CVE-2018-12561 (access restriction bypass) An issue was discovered in the cantata-mounter D-Bus service in Cantata through 2.3.1. A regular user can inject additional mount options such as file_mode= by manipulating (for example) the domain parameter of the samba URL. - CVE-2018-12562 (access restriction bypass) An issue was discovered in the cantata-mounter D-Bus service in Cantata through 2.3.1. The wrapper script 'mount.cifs.wrapper' uses the shell to forward the arguments to the actual mount.cifs binary. The shell evaluates wildcards (such as in an injected string:/home/../tmp/* string). Impact ====== An unprivileged user is able to mount remote samba shares, enabling arbitrary filesystem access and privileged escalation.

Arch Linux Security Advisory ASA-201806-11 ========================================== Severity: High Date : 2018-06-19 CVE-ID : CVE-2018-12356 Package : pass Type : arbitrary code execution Remote : Yes Link : https://security.archlinux.org/AVG-720 Summary ======= The package pass before version 1.7.2-1 is vulnerable to arbitrary code execution. Resolution ========== Upgrade to 1.7.2-1. # pacman -Syu "pass>=1.7.2-1" The problem has been fixed upstream in version 1.7.2. Workaround ========== You can make sure arbitrary code execution is not possible by disabling pass's extension facility: export PASSWORD_STORE_ENABLE_EXTENSIONS=false Description =========== An issue was discovered in password-store.sh in pass in Simple Password Store 1.7 through 1.7.1. The signature verification routine parses the output of GnuPG with an incomplete regular expression, which allows remote attackers to spoof file signatures on configuration files and extensions scripts. Modifying the configuration file allows the attacker to inject additional encryption keys under their control, thereby disclosing passwords to the attacker. Modifying the extension scripts allows the attacker arbitrary code execution. Impact ====== A remote attacker is able to bypass signature verification and register arbitrary keys for an account or execute arbitrary code on the host by providing the application a crafted pgp signature packet.

Arch Linux Security Advisory ASA-201806-10 ========================================== Severity: High Date : 2018-06-16 CVE-ID : CVE-2018-0495 Package : libgcrypt Type : private key recovery Remote : No Link : https://security.archlinux.org/AVG-719 Summary ======= The package libgcrypt before version 1.8.3-1 is vulnerable to private key recovery. Resolution ========== Upgrade to 1.8.3-1. # pacman -Syu "libgcrypt>=1.8.3-1" The problem has been fixed upstream in version 1.8.3. Workaround ========== None. Description =========== An implementation flaw has been discovered in multiple cryptographic libraries that allows a side-channel based attacker to recover ECDSA or DSA private keys. When these cryptographic libraries use the private key to create a signature, such as for a TLS or SSH connection, they inadvertently leak information through memory caches. An unprivileged attacker running on the same machine can collect the information from a few thousand signatures and recover the value of the private key. Impact ====== An unprivileged user might be able to retrieve private keys on the affected host.

[ASA-201806-8] gnupg: content spoofing
by Remi Gacogne 14 Jun '18

14 Jun '18

Arch Linux Security Advisory ASA-201806-8 ========================================= Severity: High Date : 2018-06-11 CVE-ID : CVE-2018-12020 Package : gnupg Type : content spoofing Remote : Yes Link : https://security.archlinux.org/AVG-713 Summary ======= The package gnupg before version 2.2.8-1 is vulnerable to content spoofing. Resolution ========== Upgrade to 2.2.8-1. # pacman -Syu "gnupg>=2.2.8-1" The problem has been fixed upstream in version 2.2.8. Workaround ========== None. Description =========== A security issue has been found in gnupg before 2.2.8, leading to the possibility of faking verification status of signed content. The OpenPGP protocol allows to include the file name of the original input file into a signed or encrypted message. During decryption and verification the GPG tool can display a notice with that file name. The displayed file name is not sanitized and as such may include line feeds or other control characters. This can be used inject terminal control sequences into the out and, worse, to fake the so-called status messages. These status messages are parsed by programs to get information from gpg about the validity of a signature and an other parameters. Status messages are created with the option "--status-fd N" where N is a file descriptor. Now if N is 2 the status messages and the regular diagnostic messages share the stderr output channel. By using a made up file name in the message it is possible to fake status messages. Using this technique it is for example possible to fake the verification status of a signed mail. Impact ====== A remote attacker might be able to fake the verification status of a signed e-mail or file, via a crafted file name.
