A flaw was found in Mozilla. The Mozilla Foundation Security Advisory: On Windows, an integer overflow could occur in RecordedSourceSurfaceCreation, which results in a heap buffer overflow, potentially leaking sensitive data that could have led to a sandbox escape. This bug only affects Firefox on Windows. Other operating systems are unaffected.
