high Nessus Plugin ID 183778

Language:

Synopsis

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

Description

The remote Ubuntu 18.04 ESM / 20.04 ESM / 22.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6449-1 advisory.

 - Integer Overflow vulnerability in function filter16_prewitt in libavfilter/vf_convolution.c in Ffmpeg 4.2.1, allows attackers to cause a Denial of Service or other unspecified impacts. (CVE-2020-20898)

 - A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the ff_v4l2_m2m_create_context function in v4l2_m2m.c. (CVE-2020-22038)

 - Integer Overflow vulnerability in function filter16_roberts in libavfilter/vf_convolution.c in Ffmpeg 4.2.1, allows attackers to cause a Denial of Service or other unspecified impacts. (CVE-2021-38090)

 - Integer Overflow vulnerability in function filter16_sobel in libavfilter/vf_convolution.c in Ffmpeg 4.2.1, allows attackers to cause a Denial of Service or other unspecified impacts. (CVE-2021-38091)

 - 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)

 - 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)

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

Solution

Update the affected packages.
