Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:2919-1 advisory.

- A denial of service in the subtitle decoder in FFmpeg 3.2 and 4.1 allows attackers to hog the CPU via a crafted video file in Matroska format, because handle_open_brace in libavcodec/htmlsubtitles.c has a complex format argument to sscanf. (CVE-2019-9721)

- A heap-use-after-free in the av_freep function in libavutil/mem.c of FFmpeg 4.2 allows attackers to execute arbitrary code. (CVE-2020-21688)

- A heap-use-after-free in the mpeg_mux_write_packet function in libavformat/mpegenc.c of FFmpeg 4.2 allows to cause a denial of service (DOS) via a crafted avi file. (CVE-2020-21697)

- A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the avpriv_float_dsp_allocl function in libavutil/float_dsp.c. (CVE-2020-22046)

- A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the ff_frame_pool_get function in framepool.c. (CVE-2020-22048)

- A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the wtvfile_open_sector function in wtvdec.c. (CVE-2020-22049)

- A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the av_dict_set function in dict.c. (CVE-2020-22054)

- 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

Update the affected packages.
