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.

Security readout for executives and security teams

A malicious website could crash or potentially run code in vulnerable Mozilla-based applications on Linux. The issue involved WebGL handling and Mesa graphics drivers. Practical concern is mainly legacy Linux endpoints still running very old Firefox, Thunderbird, or SeaMonkey versions. Exposure is likely limited to Linux systems running the affected legacy Mozilla versions with WebGL and Mesa drivers. Current patched Mozilla releases should not match the vulnerable version ranges described in the CVE. Treat this as a legacy exposure cleanup item unless vulnerable versions are still present. If found on managed Linux endpoints, remediate promptly because the stated impact includes remote code execution from web content. Mitigation focus: Upgrade affected Firefox, Thunderbird, and SeaMonkey installations beyond the fixed versions named by Mozilla.; Prioritize legacy Linux workstations and kiosks where old browser packages may remain installed.; Review Red Hat, Ubuntu, SUSE, and Mozilla advisories for package-specific update guidance..
