A vulnerability classified as critical has been found in Mozilla Firefox and Thunderbird 14 on Linux (Web Browser). This affects some unknown functionality of the component Mesa Driver 16 Sampler Uniform Handler. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:
The WebGL implementation in Mozilla Firefox before 15.0, Firefox ESR 10.x before 10.0.7, Thunderbird before 15.0, Thunderbird ESR 10.x before 10.0.7, and SeaMonkey before 2.12 on Linux, when a large number of sampler uniforms are used, does not properly interact with Mesa drivers, which allows remote attackers to execute arbitrary code or cause a denial of service (stack memory corruption) via a crafted web site.
The weakness was disclosed 08/28/2012 by Vladimir Vukicevic (miaubiz) as MFSA 2012-62 as confirmed advisory (Website). The advisory is shared at mozilla.org. The public release has been coordinated in cooperation with Mozilla. This vulnerability is uniquely identified as CVE-2012-3967 since 07/11/2012. The exploitability is told to be difficult. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are unknown but a private exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 03/27/2021).
It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 61721 (CentOS 5 / 6 : firefox (CESA-2012:1210)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CentOS Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 120453 (Red Hat Update for Xulrunner Firefox (RHSA-2012:1210)). Security researcher miaubiz used the Address Sanitizer tool to discover two WebGL issues. The second issue exposes a problem with Mesa drivers on Linux, leading to a potentially exploitable crash.
Upgrading to version 15 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.
The vulnerability is also documented in the vulnerability database at Tenable (61721). Further details are available at bugzilla.mozilla.org. The entries 6036, 6035, 6039 and 6040 are pretty similar.
