Arch Linux Security Advisory ASA-201701-40 ========================================== Severity: Critical Date : 2017-01-29 CVE-ID : CVE-2017-5373 CVE-2017-5375 CVE-2017-5376 CVE-2017-5378 CVE-2017-5380 CVE-2017-5383 CVE-2017-5390 CVE-2017-5396 Package : thunderbird Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-158 Summary ======= The package thunderbird before version 45.7.0-1 is vulnerable to multiple issues including arbitrary code execution, information disclosure, privilege escalation and content spoofing. Resolution ========== Upgrade to 45.7.0-1. # pacman -Syu "thunderbird>=45.7.0-1" The problems have been fixed upstream in version 45.7.0. Workaround ========== None. Description =========== - CVE-2017-5373 (arbitrary code execution) Several memory safety bugs have been found in Firefox < 51 and Thunderbird < 47.5. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. - CVE-2017-5375 (arbitrary code execution) JIT code allocation in Firefox < 51 and Thunderbird < 45.7 can allow for a bypass of ASLR and DEP protections leading to potential memory corruption attacks. - CVE-2017-5376 (arbitrary code execution) A use-after-free vulnerability has been found in Firefox < 51 and Thunderbird < 45.7, while manipulating XSL in XSLT documents. - CVE-2017-5378 (information disclosure) An information disclosure vulnerability has been found in Firefox < 51 and Thunderbird < 45.7, where hashed codes of JavaScript objects are shared between pages. This allows for pointer leaks because an object’s address can be discovered through hash codes, and also allows for data leakage of an object’s content using these hash codes. - CVE-2017-5380 (arbitrary code execution) A potential use-after-free vulnerability during DOM manipulation of SVG content has been in Firefox < 51 and Thunderbird < 45.7. - CVE-2017-5383 (content spoofing) URLs containing certain unicode glyphs for alternative hyphens and quotes do not properly trigger punycode display in Firefox < 51 and Thunderbird < 45.7, allowing for domain name spoofing attacks in the location bar. - CVE-2017-5390 (privilege escalation) The JSON viewer in the Developer Tools in Firefox < 51 and Thunderbird < 45.7 uses insecure methods to create a communication channel for copying and viewing JSON or HTTP headers data, allowing for potential privilege escalation. - CVE-2017-5396 (arbitrary code execution) A use-after-free vulnerability has been found in the Media Decoder of Firefox < 51 and Thunderbird < 45.7, when working with media files when some events are fired after the media elements are freed from memory. Impact ====== A remote attacker can access sensitive information, spoof content, escalate privileges and execute arbitrary code on the affected host.

Resolution ========== Upgrade to 51.0.1-1. # pacman -Syu "firefox>=51.0.1-1" The problems have been fixed upstream in version 51.0. Workaround ========== None. Description =========== - CVE-2017-5373 (arbitrary code execution) Several memory safety bugs have been found in Firefox < 51 and Thunderbird < 47.5. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. - CVE-2017-5374 (arbitrary code execution) Several memory safety bugs have been found in Firefox < 51. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. - CVE-2017-5375 (arbitrary code execution) JIT code allocation in Firefox < 51 and Thunderbird < 45.7 can allow for a bypass of ASLR and DEP protections leading to potential memory corruption attacks. - CVE-2017-5376 (arbitrary code execution) A use-after-free vulnerability has been found in Firefox < 51 and Thunderbird < 45.7, while manipulating XSL in XSLT documents. - CVE-2017-5377 (arbitrary code execution) A memory corruption vulnerability in Skia that can occur when using transforms to make gradients, resulting in a potentially exploitable crash. - CVE-2017-5378 (information disclosure) An information disclosure vulnerability has been found in Firefox < 51 and Thunderbird < 45.7, where hashed codes of JavaScript objects are shared between pages. This allows for pointer leaks because an object’s address can be discovered through hash codes, and also allows for data leakage of an object’s content using these hash codes. - CVE-2017-5379 (arbitrary code execution) A use-after-free vulnerability has been found in Firefox < 51, in Web Animations, when interacting with cycle collection. - CVE-2017-5380 (arbitrary code execution) A potential use-after-free vulnerability during DOM manipulation of SVG content has been in Firefox < 51 and Thunderbird < 45.7. - CVE-2017-5381 (arbitrary file overwrite) The "export" function in the Firefox < 51 Certificate Viewer can force local filesystem navigation when the "common name" in a certificate contains slashes, allowing certificate content to be saved in unsafe locations with an arbitrary filename. - CVE-2017-5382 (information disclosure) Feed preview for RSS feeds in Firefox < 51 can be used to capture errors and exceptions generated by privileged content, allowing for the exposure of internal information not meant to be seen by web content. - CVE-2017-5383 (content spoofing) URLs containing certain unicode glyphs for alternative hyphens and quotes do not properly trigger punycode display in Firefox < 51 and Thunderbird < 45.7, allowing for domain name spoofing attacks in the location bar. - CVE-2017-5384 (information disclosure) Proxy Auto-Config (PAC) files in Firefox < 51 can specify a JavaScript function called for all URL requests with the full URL path which exposes more information than would be sent to the proxy itself in the case of HTTPS. Normally the Proxy Auto-Config file is specified by the user or machine owner and presumed to be non-malicious, but if a user has enabled Web Proxy Auto Detect (WPAD) this file can be served remotely. - CVE-2017-5385 (information disclosure) In Firefox < 51, data sent with in multipart channels, such as the multipart/x-mixed-replace MIME type, will ignore the referrer-policy response header, leading to potential information disclosure for sites using this header. - CVE-2017-5386 (privilege escalation) WebExtension scripts in Firefox < 51 can use the data: protocol to affect pages loaded by other web extensions using this protocol, leading to potential data disclosure or privilege escalation in affected extensions. - CVE-2017-5387 (information disclosure) The existence of a specifically requested local file can be found in Firefox < 51 due to the double firing of the onerror when the source attribute on a <track> tag refers to a file that does not exist if the source page is loaded locally. - CVE-2017-5388 (denial of service) In Firefox < 51, a STUN server in conjunction with a large number of webkitRTCPeerConnection objects can be used to send large STUN packets in a short period of time due to a lack of rate limiting being applied on e10s systems, allowing for a denial of service attack. - CVE-2017-5389 (access restriction bypass) WebExtensions in Firefox < 51 could use the mozAddonManager API by modifying the CSP headers on sites with the appropriate permissions and then using host requests to redirect script loads to a malicious site. This allows a malicious extension to then install additional extensions without explicit user permission. - CVE-2017-5390 (privilege escalation) The JSON viewer in the Developer Tools in Firefox < 51 and Thunderbird < 45.7 uses insecure methods to create a communication channel for copying and viewing JSON or HTTP headers data, allowing for potential privilege escalation. - CVE-2017-5391 (privilege escalation) In Firefox < 51, special about: pages used by web content, such as RSS feeds, can load privileged about: pages in an iframe. If a content- injection bug were found in one of those pages this could allow for potential privilege escalation. - CVE-2017-5393 (access restriction bypass) The mozAddonManager in Firefox < 51 allows for the installation of extensions from the CDN for addons.mozilla.org, a publicly accessible site. This could allow malicious extensions to install additional extensions from the CDN in combination with an XSS attack on Mozilla AMO sites. - CVE-2017-5396 (arbitrary code execution) A use-after-free vulnerability has been found in the Media Decoder of Firefox < 51 and Thunderbird < 45.7, when working with media files when some events are fired after the media elements are freed from memory. Impact ====== A remote attacker can access sensitive information, bypass access restrictions, overwrite arbitrary files, spoof content, escalate privileges and execute arbitrary code on the affected host.

Arch Linux Security Advisory ASA-201701-38 ========================================== Severity: Medium Date : 2017-01-29 CVE-ID : CVE-2017-2583 Package : linux-zen Type : privilege escalation Remote : No Link : https://security.archlinux.org/AVG-151 Summary ======= The package linux-zen before version 4.9.5-1 is vulnerable to privilege escalation. Resolution ========== Upgrade to 4.9.5-1. # pacman -Syu "linux-zen>=4.9.5-1" The problem has been fixed upstream in version 4.9.5. Workaround ========== None. Description =========== The Linux kernel > 3.6-rc1, when built with Kernel-based Virtual Machine (CONFIG_KVM) support, is vulnerable to an incorrect segment selector (SS) value error. It could occur loading values into SS register in long mode. A user/process inside a guest host could use this flaw to crash the guest, resulting in denial of service, or potentially escalate their privileges inside the guest system on an AMD processor. Impact ====== A local attacker in a guest host is able to crash the system or escalate privileges inside the guest on an AMD processor.

Arch Linux Security Advisory ASA-201701-37 ========================================== Severity: Medium Date : 2017-01-28 CVE-ID : CVE-2016-7055 CVE-2017-3731 CVE-2017-3732 Package : openssl Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-154 Summary ======= The package openssl before version 1.0.2.k-1 is vulnerable to multiple issues including denial of service, incorrect calculation and information disclosure. Resolution ========== Upgrade to 1.0.2.k-1. # pacman -Syu "openssl>=1.0.2.k-1" The problems have been fixed upstream in version 1.0.2.k. Workaround ========== None. Description =========== - CVE-2016-7055 (incorrect calculation) There is a carry propagating bug in the Broadwell-specific Montgomery multiplication procedure that handles input lengths divisible by, but longer than 256 bits. Analysis suggests that attacks against RSA, DSA and DH private keys are impossible. This is because the subroutine in question is not used in operations with the private key itself and an input of the attacker's direct choice. Otherwise the bug can manifest itself as transient authentication and key negotiation failures or reproducible erroneous outcome of public-key operations with specially crafted input. Among EC algorithms only Brainpool P-512 curves are affected and one presumably can attack ECDH key negotiation. Impact was not analyzed in detail, because pre-requisites for attack are considered unlikely. Namely multiple clients have to choose the curve in question and the server has to share the private key among them, neither of which is default behavior. Even then only clients that chose the curve will be affected. - CVE-2017-3731 (denial of service) If an SSL/TLS server or client is running on a 32-bit host, and a specific cipher is being used, then a truncated packet can cause that server or client to perform an out-of-bounds read, usually resulting in a crash. For OpenSSL 1.1.0, the crash can be triggered when using CHACHA20/POLY1305; users should upgrade to 1.1.0d. For Openssl 1.0.2, the crash can be triggered when using RC4-MD5; users who have not disabled that algorithm should update to 1.0.2k. - CVE-2017-3732 (information disclosure) There is a carry propagating bug in the x86_64 Montgomery squaring procedure. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be very significant and likely only accessible to a limited number of attackers. An attacker would additionally need online access to an unpatched system using the target private key in a scenario with persistent DH parameters and a private key that is shared between multiple clients. For example this can occur by default in OpenSSL DHE based SSL/TLS ciphersuites. Note: This issue is very similar to CVE-2015-3193 but must be treated as a separate problem. Impact ====== A remote attacker is able to crash the application, access sensitive information or transiently authenticate against the server.
