The remote host is affected by the vulnerability described in GLSA-202312-14 (FFmpeg: Multiple Vulnerabilities)

  - dwa_uncompress in libavcodec/exr.c in FFmpeg 4.4 allows an out-of-bounds array access because dc_count is     not strictly checked. (CVE-2021-33815)

  - adts_decode_extradata in libavformat/adtsenc.c in FFmpeg 4.4 does not check the init_get_bits return     value, which is a necessary step because the second argument to init_get_bits can be crafted.
    (CVE-2021-38171)

  - FFmpeg version (git commit de8e6e67e7523e48bb27ac224a0b446df05e1640) suffers from a an assertion failure     at src/libavutil/mathematics.c. (CVE-2021-38291)

  - An integer overflow vulnerability was found in FFmpeg versions before 4.4.2 and before 5.0.1 in     g729_parse() in llibavcodec/g729_parser.c when processing a specially crafted file. (CVE-2022-1475)

  - A vulnerability classified as problematic has been found in ffmpeg. This affects an unknown part of the     file libavcodec/rpzaenc.c of the component QuickTime RPZA Video Encoder. The manipulation of the argument     y_size leads to out-of-bounds read. It is possible to initiate the attack remotely. The name of the patch     is 92f9b28ed84a77138105475beba16c146bdaf984. It is recommended to apply a patch to fix this issue. The     associated identifier of this vulnerability is VDB-213543. (CVE-2022-3964)

  - A vulnerability classified as problematic was found in ffmpeg. This vulnerability affects the function     smc_encode_stream of the file libavcodec/smcenc.c of the component QuickTime Graphics Video Encoder. The     manipulation of the argument y_size leads to out-of-bounds read. The attack can be initiated remotely. The     name of the patch is 13c13109759090b7f7182480d075e13b36ed8edd. It is recommended to apply a patch to fix     this issue. The identifier of this vulnerability is VDB-213544. (CVE-2022-3965)

  - libavcodec/pthread_frame.c in FFmpeg before 5.1.2, as used in VLC and other products, leaves stale hwaccel     state in worker threads, which allows attackers to trigger a use-after-free and execute arbitrary code in     some circumstances (e.g., hardware re-initialization upon a mid-video SPS change when Direct3D11 is used).
    (CVE-2022-48434)
