CVE-2021-36409

CVSS v2.0

9.3

High

VectorAV:N/AC:M/Au:N/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions libde265 version 1.0.8
Description The issue is related to the insufficient use of the assert() function in the sps.cc component of the libde265 h.265 video codec implementation. This can be exploited by a remote attacker using a specially crafted file, potentially allowing access to confidential data, disrupting data integrity, and causing a denial of service. The vulnerability is triggered when decoding a file fails the scaling list pred matrix id delta==1 assertion at sps.cc:925.
Recommendations For libde265 version 1.0.8, consider disabling the assert() function in the sps.cc component or restricting the use of the vulnerable video codec implementation until a patch is available. As a temporary workaround, avoid using the libde265 library with untrusted input files to minimize the risk of exploitation.
