Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS : Software Properties vulnerability (USN-4457-1)

medium Nessus Plugin ID 139568

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-4457-1 advisory.

 Jason A. Donenfeld discovered that Software Properties incorrectly filtered certain escape sequences when displaying PPA descriptions. If a user were tricked into adding an arbitrary PPA, a remote attacker could possibly manipulate the screen.

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.
