Synopsis

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

Description

The remote SUSE Linux SLED15 / SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:3521-1 advisory.

- Buffer Overflow vulnerability in function config_input in libavfilter/vf_gblur.c in Ffmpeg 4.2.1, allows attackers to cause a Denial of Service or other unspecified impacts. (CVE-2020-20891)

- An issue was discovered in function filter_frame in libavfilter/vf_lenscorrection.c in Ffmpeg 4.2.1, allows attackers to cause a Denial of Service or other unspecified impacts due to a division by zero.
(CVE-2020-20892)

- An issue was discovered in function latm_write_packet in libavformat/latmenc.c in Ffmpeg 4.2.1, allows attackers to cause a Denial of Service or other unspecified impacts due to a Null pointer dereference.
(CVE-2020-20896)

- A CWE-125: Out-of-bounds read vulnerability exists in long_term_filter function in g729postfilter.c in FFmpeg 4.2.1 during computation of the denominator of pseudo-normalized correlation R'(0), that could result in disclosure of information. (CVE-2020-20902)

- A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in avcodec_alloc_context3 at options.c. (CVE-2020-22037)

- decode_frame in libavcodec/exr.c in FFmpeg 4.3.1 has an out-of-bounds write because of errors in calculations of when to perform memset zero operations. (CVE-2020-35965)

- 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)

- Integer Overflow vulnerability in function filter_prewitt in libavfilter/vf_convolution.c in Ffmpeg 4.2.1, allows attackers to cause a Denial of Service or other unspecified impacts. (CVE-2021-38092)

- Integer Overflow vulnerability in function filter_robert in libavfilter/vf_convolution.c in Ffmpeg 4.2.1, allows attackers to cause a Denial of Service or other unspecified impacts. (CVE-2021-38093)

- Integer Overflow vulnerability in function filter_sobel in libavfilter/vf_convolution.c in Ffmpeg 4.2.1, allows attackers to cause a Denial of Service or other unspecified impacts. (CVE-2021-38094)

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