Name of the Vulnerable Software and Affected Versions Libde265 version 1.0.8

Description The issue is related to a heap-buffer-overflow vulnerability in the put epel 16 fallback() function of the Libde265 video codec implementation for h.265. This vulnerability can be exploited by a remote attacker using a specially crafted video file, potentially leading to a Denial of Service (DoS). The vulnerability is caused by the put epel 16 fallback() function in fallback-motion.cc.

Recommendations For Libde265 version 1.0.8, update to version 1.0.11 to fix the security issues. As a temporary workaround, consider restricting the use of the put epel 16 fallback() function in fallback-motion.cc until a patch is available. Avoid using crafted video files that could exploit this vulnerability.
