high Nessus Plugin ID 154053

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-5078-3 advisory.

 USN-5078-1 fixed a vulnerability in Squashfs-Tools. That update was incomplete and could still result in Squashfs-Tools mishandling certain malformed SQUASHFS files. This update fixes the problem.

 We apologize for the inconvenience.



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 squashfs-tools package.
