CVE-2019-11710: Mozilla Firefox vulnerability

CVE-2019-11710: Mozilla developers and community members reported memory safety bugs present in Firefox 67.

Mozilla developers and community members reported memory safety bugs present in Firefox 67. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox < 68.

Security readout for executives and security teams

CVE-2019-11710 covers memory safety bugs in Firefox 67. Mozilla says some showed memory corruption and could, with enough effort, be exploited to run arbitrary code. Organizations still running Firefox before 68 should treat this as an urgent legacy browser update issue, not a confirmed active exploitation event. Exposure is likely limited to endpoints, servers, or packaged environments still running Firefox versions before 68, including downstream Linux distribution packages that were later covered by Gentoo and openSUSE advisories. Prioritize remediation for any remaining legacy Firefox installations. The business risk is arbitrary code execution through a browser memory-corruption class, but the supplied evidence does not show active exploitation. Mitigation focus: Upgrade Firefox to version 68 or later, or a vendor-supported fixed package.; Prioritize internet-browsing endpoints and shared workstations running legacy Firefox.; Review Gentoo or openSUSE advisories if those distributions manage Firefox packages..
