Name of the Vulnerable Software and Affected Versions libde265 version 1.0.12

Description The issue is related to a buffer overflow in the libde265 video codec implementation, specifically concerning the allocation size exceeding the maximum supported size of 0x10000000000. This can be exploited by an attacker to cause a denial of service. The exploitation does not require local access, as a remote attacker can also trigger the issue.

Recommendations For libde265 version 1.0.12, consider applying a patch or update that fixes the buffer overflow issue, if available. As a temporary workaround, restrict the allocation size to prevent it from exceeding the maximum supported size of 0x10000000000.
