CVE-2019-9792

Priority
Description
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.
