CVE-2024-10468Network attack vector

Memory corruption via unsynchronized IndexedDB hash-table access

Published Oct 29, 2024 · Updated Oct 29, 2024

Race conditions in IndexedDB in Mozilla Firefox and Thunderbird before 132 allow attackers to corrupt memory via concurrent database operations. FileInfoManager permits mFileInfos hash-table access from ActorsParent and FileInfoManager paths without consistently holding the shared mutex. The observed failure manifests only in debug builds; it can crash the application, while code execution has not been demonstrated.
