Security readout for executives and security teams

CVE-2016-1962 is a memory-safety flaw in Firefox's WebRTC data-channel handling. A remote attacker could potentially run code through mishandled data-channel connection closure. The source bundle identifies Firefox before 45.0 and Firefox ESR 38.x before 38.7 as affected. Exposure is most likely on systems still running Mozilla Firefox before 45.0 or Firefox ESR 38.x before 38.7, including vendor-packaged builds covered by Linux distribution advisories. Prioritize remediation where legacy Firefox remains installed. The issue is old, but remote code execution in a browser can create meaningful endpoint risk if obsolete software persists. Mitigation focus: Upgrade Firefox to 45.0 or later where applicable.; Upgrade Firefox ESR to 38.7 or later where applicable.; Apply relevant Linux distribution security updates for packaged Firefox builds..
