CVE-2016-1962 is a critical use-after-free vulnerability in the mozilla::DataChannelConnection::Close function within Mozilla Firefox (versions before 45.0 and ESR 38.x before 38.7) and related distributions like OpenSUSE and Oracle Linux. This flaw allows remote attackers to execute arbitrary code by manipulating WebRTC data-channel connections. With a CVSS v3 score of 9.8, it presents a high-impact threat with low attack complexity, potentially leading to complete compromise of confidentiality, integrity, and availability. While not listed in CISA's KEV catalog and lacking public exploit intelligence (Metasploit, Nuclei, ExploitDB), its high FAUCET Risk Score of 81/100 and media coverage indicate significant concern at the time of discovery.
