CVE-2016-1935

27
FAUCET Score

CVE-2016-1935 describes a critical buffer overflow vulnerability in Mozilla Firefox versions prior to 44.0 and Firefox ESR 38.x before 38.6. This flaw, residing in the BufferSubData function, allows remote attackers to execute arbitrary code by enticing users to view specially crafted WebGL content. With a CVSS v3 score of 8.8 (High), this vulnerability poses a significant risk due to its network-based attack vector, low attack complexity, and potential for complete compromise of confidentiality, integrity, and availability. Despite its severity, there is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
