CVE-2021-36409

There is an Assertion `scaling_list_pred_matrix_id_delta==1' failed at sps.cc:925 in libde265 v1.0.8 when decoding file, which allows attackers to cause a Denial of Service (DoS) by running the application with a crafted file or possibly have unspecified other impact.

CVE-2021-36410

A stack-buffer-overflow exists in libde265 v1.0.8 via fallback-motion.cc in function put_epel_hv_fallback when running program dec265.

CVE-2021-36411

An issue has been found in libde265 v1.0.8 due to incorrect access control. A SEGV caused by a READ memory access in function derive_boundaryStrength of deblock.cc has occurred. The vulnerability causes a segmentation fault and application crash, which leads to remote denial of service.
