Integer Overflow in RecordedSourceSurfaceCreation
On Windows, an integer overflow could occur in `RecordedSourceSurfaceCreation` which resulted 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.* This vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and Thunderbird < 115.2.
