**Name of the Vulnerable Software and Affected Versions** libjxl versions prior to 0.8.2 **Description** An issue in dec patch dictionary.cc can lead to a denial of service due to an integer underflow in patch decoding, potentially causing an infinite loop. The issue can be exploited by a remote attacker to disrupt service. **Recommendations** For versions prior to 0.8.2, update to version 0.8.2 or later to resolve the issue. As a temporary workaround, consider restricting the use of the dec patch dictionary.cc component until a patch is available.
