Ubuntu 16.04 LTS / 18.04 LTS : Evince update (USN-4024-1)

high Nessus Plugin ID 126068

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

As a security improvement, this update adjusts the AppArmor profile for the Evince thumbnailer to reduce access to the system and adjusts the AppArmor profile for Evince and Evince previewer to limit access to the DBus system bus. Additionally adjust the evince abstraction to disallow writes on parent directories of sensitive files.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
