Apple macOS < 10.14.5 / iOS < 12.3 DFG JIT Compiler - 'HasIndexedProperty' Use-After-Free
See also https://bugs.chromium.org/p/project-zero/issues/detail?id=1699 for a similar issue. The DFG JIT compiler attempts to determine whether a DFG IR operation could cause garbage collection GC during its execution 1. With this, it is then possible for the compiler to determine whether there...
Buffer Overflow
Mozilla Thunderbird is vulnerable to buffer overflow. It does not use correct alias information in IonMonkey JIT compiler for MArraySlice in Array.prototype.slice method...
Missing Null Check
Eclipse OpenJ9 is vulnerable to missing null check vulnerability. This occurs in a part of the component JIT Compiler because the OpenJ9 JIT compiler incorrectly omits a null check on the receiver object of an Unsafe call when accelerating it...
Arbitrary Code Execution
Firefox and Firefox ESR are vulnerable to arbitrary code execution attacks. A remote user could trigger a bailout error in the JavaScript JIT compiler when inlining 'Array.prototype.push' to potentially execute arbitrary code within the sandboxed content process which may lead to disclosure of...
Mozilla: IonMonkey leaks JS_OPTIMIZED_OUT magic value to script
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...
