high Nessus Plugin ID 152737

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2742 advisory.

- Buffer Overflow vulnerability exists in FFmpeg 4.1 via apng_do_inverse_blend in libavcodec/pngenc.c, which could let a remote malicious user cause a Denial of Service (CVE-2020-21041)

- Buffer Overflow vulnerability in FFmpeg 4.2 in mov_write_video_tag due to the out of bounds in libavformat/movenc.c, which could let a remote malicious user obtain sensitive information, cause a Denial of Service, or execute arbitrary code. (CVE-2020-22015)

- A heap-based Buffer Overflow vulnerability in FFmpeg 4.2 at libavcodec/get_bits.h when writing .mov files, which might lead to memory corruption and other potential consequences. (CVE-2020-22016)

- Buffer Overflow vulnerability in FFmpeg 4.2 in the build_diff_map function in libavfilter/vf_fieldmatch.c, which could let a remote malicious user cause a Denial of Service. (CVE-2020-22020)

- Buffer Overflow vulnerability in FFmpeg 4.2 at filter_edges function in libavfilter/vf_yadif.c, which could let a remote malicious user cause a Denial of Service. (CVE-2020-22021)

- A heap-based Buffer Overflow vulnerability exists in FFmpeg 4.2 in filter_frame at libavfilter/vf_fieldorder.c, which might lead to memory corruption and other potential consequences.
(CVE-2020-22022)

- A heap-based Buffer Overflow vulnerabililty exists in FFmpeg 4.2 in filter_frame at libavfilter/vf_bitplanenoise.c, which might lead to memory corruption and other potential consequences.
(CVE-2020-22023)

- A heap-based Buffer Overflow vulnerability exists in gaussian_blur at libavfilter/vf_edgedetect.c, which might lead to memory corruption and other potential consequences. (CVE-2020-22025)

- Buffer Overflow vulnerability exists in FFmpeg 4.2 in the config_input function at libavfilter/af_tremolo.c, which could let a remote malicious user cause a Denial of Service.
(CVE-2020-22026)

- Buffer Overflow vulnerability exists in FFmpeg 4.2 in filter_vertically_8 at libavfilter/vf_avgblur.c, which could cause a remote Denial of Service. (CVE-2020-22028)

- A Heap-based Buffer Overflow vulnerability exists in FFmpeg 4.2 at libavfilter/vf_w3fdif.c in filter16_complex_low, which might lead to memory corruption and other potential consequences.
(CVE-2020-22031)

- A heap-based Buffer Overflow vulnerability exists FFmpeg 4.2 at libavfilter/vf_edgedetect.c in gaussian_blur, which might lead to memory corruption and other potential consequences. (CVE-2020-22032)

- A heap-based Buffer Overflow vulnerability exists in FFmpeg 4.2 in filter_intra at libavfilter/vf_bwdif.c, which might lead to memory corruption and other potential consequences. (CVE-2020-22036)

- Prior to ffmpeg version 4.3, the tty demuxer did not have a 'read_probe' function assigned to it. By crafting a legitimate ffconcat file that references an image, followed by a file the triggers the tty demuxer, the contents of the second file will be copied into the output file verbatim (as long as the `-vcodec copy` option is passed to ffmpeg). (CVE-2021-3566)

- libavcodec/dnxhddec.c in FFmpeg 4.4 does not check the return value of the init_vlc function, a similar issue to CVE-2013-0868. (CVE-2021-38114)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the ffmpeg packages.

For Debian 9 stretch, these problems have been fixed in version 7
