Ubuntu 14.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 26.04 LTS : GStreamer Bad Plugins vulnerability (USN-8855-1)

high Nessus Plugin ID 362502

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 26.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-8855-1 advisory.

 It was discovered that GStreamer Bad Plugins incorrectly validated the size of multi-channel audio blocks.
 An attacker could possibly use this

 issue with a specially crafted WAV file to cause the program to crash, resulting in a denial of service, or possibly execute arbitrary code.

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

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.
