Name of the Vulnerable Software and Affected Versions libde265 version 1.0.10

Description The issue is related to a NULL pointer dereference in the mc chroma function at motion.cc in the libde265 video codec implementation. This allows an attacker to cause a Denial of Service (DoS) via a crafted input file. The exploitation of this issue can be done remotely.

Recommendations For libde265 version 1.0.10, update to version 1.0.11 to fix the security issues. As a temporary workaround, consider restricting the use of the mc chroma function in motion.cc to minimize the risk of exploitation. Avoid using crafted input files that could trigger the NULL pointer dereference in the mc chroma function until the issue is resolved.
