  - An Incorrect Access Control vulnerability exists in libde265 v1.0.8 due to a SEGV in slice.cc.
    (CVE-2021-35452)

  - An issue was discovered in libde265 v1.0.8.There is a Heap-use-after-free in intrapred.h when decoding
    file using dec265. (CVE-2021-36408)

  - 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-2021-36409)

  - 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-2021-36410)

  - 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. (CVE-2021-36411)

  - Heap-based Buffer Overflow in GitHub repository strukturag/libde265 prior to and including 1.0.8. The fix
    is established in commit 8e89fe0e175d2870c39486fdd09250b230ec10b8 but does not yet belong to an official
    release. (CVE-2022-1253)

  - Libde265 v1.0.8 was discovered to contain a heap-buffer-overflow vulnerability via
    ff_hevc_put_hevc_epel_pixels_8_sse in sse-motion.cc. This vulnerability allows attackers to cause a Denial
    of Service (DoS) via a crafted video file. (CVE-2022-43235)

  - Libde265 v1.0.8 was discovered to contain a stack-buffer-overflow vulnerability via
    put_qpel_fallback<unsigned short> in fallback-motion.cc. This vulnerability allows attackers to cause a
    Denial of Service (DoS) via a crafted video file. (CVE-2022-43236)

  - Libde265 v1.0.8 was discovered to contain a stack-buffer-overflow vulnerability via void
    put_epel_hv_fallback<unsigned short> in fallback-motion.cc. This vulnerability allows attackers to cause a
    Denial of Service (DoS) via a crafted video file. (CVE-2022-43237)

  - Libde265 v1.0.8 was discovered to contain an unknown crash via ff_hevc_put_hevc_qpel_h_3_v_3_sse in sse-
    motion.cc. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted video
    file. (CVE-2022-43238)

  - Libde265 v1.0.8 was discovered to contain a heap-buffer-overflow vulnerability via mc_chroma<unsigned
    short> in motion.cc. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted
    video file. (CVE-2022-43239)

  - Libde265 v1.0.8 was discovered to contain a heap-buffer-overflow vulnerability via
    ff_hevc_put_hevc_qpel_h_2_v_1_sse in sse-motion.cc. This vulnerability allows attackers to cause a Denial
    of Service (DoS) via a crafted video file. (CVE-2022-43240)

  - Libde265 v1.0.8 was discovered to contain an unknown crash via ff_hevc_put_hevc_qpel_v_3_8_sse in sse-
    motion.cc. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted video
    file. (CVE-2022-43241)

  - Libde265 v1.0.8 was discovered to contain a heap-buffer-overflow vulnerability via mc_luma<unsigned char>
    in motion.cc. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted video
    file. (CVE-2022-43242)

  - Libde265 v1.0.8 was discovered to contain a heap-buffer-overflow vulnerability via
    ff_hevc_put_weighted_pred_avg_8_sse in sse-motion.cc. This vulnerability allows attackers to cause a
    Denial of Service (DoS) via a crafted video file. (CVE-2022-43243)

  - Libde265 v1.0.8 was discovered to contain a heap-buffer-overflow vulnerability via
    put_weighted_pred_avg_16_fallback in fallback-motion.cc. This vulnerability allows attackers to cause a
    Denial of Service (DoS) via a crafted video file. (CVE-2022-43248)

  - Libde265 v1.0.8 was discovered to contain a heap-buffer-overflow vulnerability via put_epel_16_fallback in
    fallback-motion.cc. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted
    video file. (CVE-2022-43252)

  - Libde265 v1.0.8 was discovered to contain a heap-buffer-overflow vulnerability via
    put_unweighted_pred_16_fallback in fallback-motion.cc. This vulnerability allows attackers to cause a
    Denial of Service (DoS) via a crafted video file. (CVE-2022-43253)
