of Service (DoS) via a crafted input file.

CVE-2023-24754

libde265 v1.0.10 was discovered to contain a NULL pointer
dereference in the ff_hevc_put_weighted_pred_avg_8_sse function at
sse-motion.cc. This vulnerability allows attackers to cause a Denial
of Service (DoS) via a crafted input file.

CVE-2023-24755

libde265 v1.0.10 was discovered to contain a NULL pointer
dereference in the put_weighted_pred_8_fallback function at
fallback-motion.cc. This vulnerability allows attackers to cause a
Denial of Service (DoS) via a crafted input file.

CVE-2023-24756

libde265 v1.0.10 was discovered to contain a NULL pointer
dereference in the ff_hevc_put_unweighted_pred_8_sse function at
sse-motion.cc. This vulnerability allows attackers to cause a Denial
of Service (DoS) via a crafted input file.

CVE-2023-24757

libde265 v1.0.10 was discovered to contain a NULL pointer
dereference in the put_unweighted_pred_16_fallback function at
fallback-motion.cc. This vulnerability allows attackers to cause a
Denial of Service (DoS) via a crafted input file.

CVE-2023-24758

libde265 v1.0.10 was discovered to contain a NULL pointer
dereference in the ff_hevc_put_weighted_pred_avg_8_sse function at
sse-motion.cc. This vulnerability allows attackers to cause a Denial
of Service (DoS) via a crafted input file.

CVE-2023-25221

Libde265 v1.0.10 was discovered to contain a heap-buffer-overflow
vulnerability in the derive_spatial_luma_vector_prediction function
in motion.cc.

For Debian 10 buster, these problems have been fixed in version
