Name of the Vulnerable Software and Affected Versions Libde265 versions 1.0.8

Description The issue is related to a heap-buffer-overflow vulnerability via the put qpel fallback<unsigned short> function in fallback-motion.cc. This allows attackers to cause a Denial of Service (DoS) via a crafted video file. The vulnerability is associated with a buffer overflow in the h.265 video codec implementation.

Recommendations For Libde265 version 1.0.8, update to version 1.0.11 to fix the security issue. As a temporary workaround, consider restricting the use of the put qpel fallback function in fallback-motion.cc to minimize the risk of exploitation.
