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

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...

Trashing the Flow of Data

Posted by Stephen Röttger In this blog post I want to present crbug.com/944062, a vulnerability in Chrome’s JavaScript compiler TurboFan that was discovered independently by Samuel saelo@ via fuzzing with fuzzilli, and by myself via manual code auditing. The bug was found in beta and was fixed...

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...
