Arch Linux Security Advisory ASA-201612-15 ========================================== Severity: Critical Date : 2016-12-14 CVE-ID : CVE-2016-9080 CVE-2016-9893 CVE-2016-9894 CVE-2016-9895 CVE-2016-9896 CVE-2016-9897 CVE-2016-9898 CVE-2016-9899 CVE-2016-9900 CVE-2016-9901 CVE-2016-9902 CVE-2016-9903 CVE-2016-9904 Package : firefox Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-106 Summary ======= The package firefox before version 50.1.0-1 is vulnerable to multiple issues including arbitrary code execution, access restriction bypass, information disclosure, content spoofing, cross-site scripting and insufficient validation. Resolution ========== Upgrade to 50.1.0-1. # pacman -Syu "firefox>=50.1.0-1" The problems have been fixed upstream in version 50.1.0. Workaround ========== None. Description =========== - CVE-2016-9080 (arbitrary code execution) Mozilla developers and community members Kan-Ru Chen, Christian Holler, and Tyson Smith reported memory safety bugs present in Firefox 50.0.2. 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-2016-9893 (arbitrary code execution) Mozilla developers and community members Jan de Mooij, Iris Hsiao, Christian Holler, Carsten Book, Timothy Nikkel, Christoph Diehl, Olli Pettay, Raymond Forbes, and Boris Zbarsky reported memory safety bugs present in Firefox 50.0.2 and Firefox ESR 45.5.1. 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-2016-9894 (arbitrary code execution) A buffer overflow in SkiaGl caused when a GrGLBuffer is truncated during allocation. Later writers will overflow the buffer, resulting in a potentially exploitable crash. - CVE-2016-9895 (access restriction bypass) Event handlers on marquee elements were executed despite a strict Content Security Policy (CSP) that disallowed inline JavaScript. - CVE-2016-9896 (arbitrary code execution) Use-after-free while manipulating the navigator object within WebVR. Note: WebVR is not currently enabled by default. - CVE-2016-9897 (arbitrary code execution) Memory corruption resulting in a potentially exploitable crash during WebGL functions using a vector constructor with a varying array within libGLES. - CVE-2016-9898 (arbitrary code execution) Use-after-free resulting in potentially exploitable crash when manipulating DOM subtrees in the Editor. - CVE-2016-9899 (arbitrary code execution) Use-after-free while manipulating DOM events and removing audio elements due to errors in the handling of node adoption. - CVE-2016-9900 (information disclosure) External resources that should be blocked when loaded by SVG images can bypass security restrictions through the use of data: URLs. This could allow for cross-domain data leakage. - CVE-2016-9901 (insufficient validation) HTML tags received from the Pocket server will be processed without sanitization and any JavaScript code executed will be run in the about:pocket-saved (unprivileged) page, giving it access to Pocket's messaging API through HTML injection. - CVE-2016-9902 (content spoofing) The Pocket toolbar button, once activated, listens for events fired from it's own pages but does not verify the origin of incoming events. This allows content from other origins to fire events and inject content and commands into the Pocket context. Note: this issue does not affect users with e10s enabled. - CVE-2016-9903 (cross-site scripting) Mozilla's add-ons SDK had a world-accessible resource with an HTML injection vulnerability. If an additional vulnerability allowed this resource to be loaded as a document it could allow injecting content and script into an add-on's context. - CVE-2016-9904 (information disclosure) An attacker could use a JavaScript Map/Set timing attack to determine whether an atom is used by another compartment/zone in specific contexts. This could be used to leak information, such as usernames embedded in JavaScript code, across websites. Impact ====== A remote attacker can access sensitive information, bypass security measures and execute arbitrary code on the affected host.
