NVD Description

Note: Versions mentioned in the description apply only to the upstream firefox package and not the firefox package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

The IonMonkey just-in-time (JIT) compiler can leak an internal JS_OPTIMIZED_OUT magic value to the running script during a bailout. This magic value can then be used by JavaScript to achieve memory corruption, which results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66.
