CVE-2024-2612Network attack vector

Crash or code execution via SafeRefPtr self-assignment

Published Mar 19, 2024 · Updated Feb 13, 2025

Use-after-free in Mozilla Firefox before 124, Firefox ESR before 115.9, and Thunderbird before 115.9 allows remote attackers to execute code. SafeRefPtr::operator=(SafeRefPtr&&) fails to detect self-assignment, so it releases mRawPtr while retaining a dangling pointer for later use. Reaching an affected IndexedDB code path is required; successful triggering crashes the client or runs code in its process.
