Description:   Multiple vulnerabilities were reported in Mozilla Firefox. A remote user can cause arbitrary code to be executed on the target user's system. A remote user can bypass security controls on the target system. A remote user can obtain potentially sensitive information on the target system. A remote user can conduct cross-site scripting attacks. Mozilla Thunderbird is affected.

A remote user can create specially crafted content that, when loaded by the target user, will execute arbitrary code on the target user's system.

A buffer overflow may occur in SkiaGl caused when a GrGLBuffer is truncated during allocation [CVE-2016-9894]. Mozilla ESR is not affected.

A use-after-free memory error may occur when manipulating DOM events and removing audio elements [CVE-2016-9899].

A use-after-free may occur in WebVR [CVE-2016-9896]. Mozilla ESR is not affected.

A memory corruption error may occur in libGLES [CVE-2016-9897].

A use-after-free memory may occur when manipulating DOM subtrees in the Editor [CVE-2016-9898].

Other code execution errors may occur [CVE-2016-9080, CVE-2016-9893]. Mozilla ESR is not affected by CVE-2016-9080.

A remote user can bypass inline JavaScript Content Security Policy (CSP) and cause event handlers on marquee elements to be executed [CVE-2016-9895].

A remote user can create a specially crafted SVG image that, when loaded by the target user, will access restricted external resources via 'data:' URLs [CVE-2016-9900].

A remote user can conduct a JavaScript Map/Set timing attack to obtain potentially sensitive information (e.g., usernames embedded in JavaScript code) from other domains [CVE-2016-9904].

A remote user can exploit an input validation flaw in the Pocket server to execute arbitrary JavaScript in the about:pocket-saved page and access the Pocket messaging API [CVE-2016-9901].

A remote user can exploit an origin validation flaw in the Pocket toolbar to inject content and commands into the Pocket context [CVE-2016-9902]. Systems with e10s enabled are not affected.

The add-ons SDK does not properly filter HTML code from user-supplied input before displaying the input [CVE-2016-9903]. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from an arbitrary site and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user. Mozilla ESR is not affected.

Andrew Krasichkov, Aral, Atte Kettunen, Boris Zbarsky, Carsten Book, Christian Holler, Christoph Diehl, Filipe Gomes, Iris Hsiao, Jan de Mooij, Jann Horn, Kan-Ru Chen, Kris Maglione, Nils, Olli Pettay, Raymond Forbes, Timothy Nikkel, Tyson Smith, Wladimir Palant, echo, and insertscript reported these vulnerabilities.

Impact:   A remote user can create content that, when loaded by the target user, will execute arbitrary code on the target user's system.

A remote user can bypass security controls on the target system.

A remote user can obtain potentially sensitive information on the target system.

A remote user can access the target user's cookies (including authentication cookies), if any, associated with an arbitrary site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

Solution:   Mozilla.org has issued a fix for CVE-2016-9893, CVE-2016-9895, CVE-2016-9897, CVE-2016-9898, CVE-2016-9899, CVE-2016-9900, and CVE-2016-9904 for Mozilla Thunderbird (45.6).
