CVE-2012-3967 describes a critical vulnerability in the WebGL implementation of Mozilla Firefox, Thunderbird, and SeaMonkey on Linux, specifically affecting versions before 15.0 (and ESR 10.x before 10.0.7). This flaw, triggered by a large number of sampler uniforms, improperly interacts with Mesa drivers, allowing remote attackers to execute arbitrary code or cause a denial of service through stack memory corruption via a crafted website. With a CVSS score of 9.3, this vulnerability is highly severe, requiring medium attack complexity but offering complete confidentiality, integrity, and availability impacts. Despite its severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
