CVE-2020-21597

Name of the Vulnerable Software and Affected Versions libde265 version 1.0.4

Description The issue is related to a heap buffer overflow in the mc chroma function of the libde265 video codec implementation for h.265. This can be exploited by a remote attacker using a specially crafted file, leading to a denial of service. The mc chroma function is vulnerable to buffer overflow, which can be triggered via a crafted file.

Recommendations For libde265 version 1.0.4, consider disabling the mc chroma function as a temporary workaround until a patch is available. Restrict access to the vulnerable function to minimize the risk of exploitation. Avoid using crafted files that could trigger the buffer overflow in the mc chroma function until the issue is resolved.
