Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM : FFmpeg vulnerabilities (USN-6430-1)

medium Nessus Plugin ID 182982

Language:

Synopsis

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

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6430-1 advisory.

 It was discovered that FFmpeg did not properly handle certain inputs in vf_lagfun.c, resulting in a buffer overflow vulnerability. An attacker could possibly use this issue to cause a denial of service via application crash. This issue only affected Ubuntu 20.04 LTS. (CVE-2020-22024)

 It was discovered that FFmpeg incorrectly managed memory in avienc.c, resulting in a memory leak. An attacker could possibly use this issue to cause a denial of service via application crash.
 (CVE-2020-22039)

 It was discovered that FFmpeg incorrectly handled certain files due to a memory leak in frame.c. An attacker could possibly use this issue to cause a denial of service via application crash. This issue affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2020-22040)

 It was discovered that FFmpeg incorrectly handled certain files due to a memory leak in fifo.c. An attacker could possibly use this issue to cause a denial of service via application crash.
 (CVE-2020-22043)

 It was discovered that FFmpeg incorrectly handled certain files due to a memory leak in vf_tile.c. If a user or automated system were tricked into processing a specially crafted MOV file, an attacker could possibly use this issue to cause a denial of service. (CVE-2020-22051)

 It was discovered that FFmpeg incorrectly handled certain MOV files in timecode.c, leading to an integer overflow. An attacker could possibly use this issue to cause a denial of service using a crafted MOV file.
 This issue only affected Ubuntu 16.04 LTS. (CVE-2021-28429)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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.
