CVE-2019-9791

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...

CVE-2019-9792

The IonMonkey just-in-time JIT compiler can leak an internal JSOPTIMIZEDOUT 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...
