Debian Bug     :

Multiple issues were found in libde265, an open source implementation of the
h.265 video codec, which may result in denial of service, possibly code
execution due to a heap-based buffer overflow or have unspecified other
impact.

CVE-2023-24751

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

CVE-2023-24752

    libde265 v1.0.10 was discovered to contain a NULL pointer
    dereference in the ff_hevc_put_hevc_epel_pixels_8_sse function at
    sse-motion.cc. This vulnerability allows attackers to cause a Denial
    of Service (DoS) via a crafted input file.

CVE-2023-24754

    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
1.0.11-0+deb10u4.

We recommend that you upgrade your libde265 packages.
