CVE-2019-9791

Priority
Description
The type inference system allows the compilation of functions that can
cause type confusions between arbitrary objects when compiled through the
IonMonkey just-in-time (JIT) compiler and when the constructor function is
entered through on-stack replacement (OSR). This allows for possible
arbitrary reading and writing of objects during an exploitable crash. This
vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox <
66.
