Security readout for executives and security teams
CVE-2016-9893 is a set of Mozilla memory safety bugs that could potentially allow arbitrary code execution. It affects old Firefox, Firefox ESR, and Thunderbird versions. The main business risk is legacy desktops or servers still running these outdated clients, especially where email or web content is opened. Exposure is most likely in legacy environments using unsupported Mozilla clients or old Linux distribution packages. Current patched Firefox and Thunderbird installations should not be affected by the versions named in the sources. Prioritize remediation where legacy Mozilla clients remain in production or handle untrusted web or email content. This is old, but memory corruption with possible code execution remains material if affected software still exists. Mitigation focus: Upgrade Firefox to 50.1 or later.; Upgrade Firefox ESR to 45.6 or later.; Upgrade Thunderbird to 45.6 or later..
