CVE-2011-2989

CVE-2011-2989 describes a critical vulnerability in the WebGL implementation of Mozilla Firefox 4.x-5, SeaMonkey 2.x before 2.3, and Thunderbird before 6. This flaw allows remote attackers to trigger memory corruption, leading to a denial of service or potentially arbitrary code execution. With a CVSS score of 10.0, it represents a highly severe threat due to its network-based attack vector, low attack complexity, and complete impact on confidentiality, integrity, and availability. While no active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion has been observed, the vulnerability's high severity warrants immediate patching.
