Use-after-free vulnerability in the nsHTMLDocument::SetBody function in dom/html/nsHTMLDocument.cpp in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7 allows remote attackers to execute arbitrary code by leveraging mishandling of a root element, aka ZDI-CAN-3574.

Security readout for executives and security teams

CVE-2016-1961 is a memory safety flaw in older Mozilla Firefox versions. A malicious website could potentially make the browser misuse freed memory and run attacker-controlled code. The source bundle names Firefox before 45.0 and Firefox ESR 38.x before 38.7 as affected. Exposure is most likely on endpoints or servers still running Firefox before 45.0 or Firefox ESR 38.x before 38.7, including distribution-packaged builds referenced by Ubuntu, Debian, SUSE, openSUSE, and Gentoo advisories. Treat this as a high-priority legacy browser remediation issue. The business risk comes from remote code execution in end-user browsing, but urgency depends on whether affected 2016-era Firefox builds still exist in your environment. Mitigation focus: Upgrade Firefox to 45.0 or later where applicable.; Upgrade Firefox ESR 38.x to 38.7 or later.; Apply relevant Linux distribution security updates for packaged Firefox builds..
