USN-4024-1: Evince update

evince update

A security issue affects these releases of Ubuntu and its derivatives:

Ubuntu 18.04 LTS
Ubuntu 16.04 LTS

Summary

Use more restrictive AppArmor policy for Evince binaries.

Software Description

evince – Document viewer

Details

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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 18.04 LTS: evince-common – 3.28.4-0ubuntu1.2
Ubuntu 16.04 LTS: evince-common – 3.18.2-1ubuntu4.5

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

In general, a standard system update will make all the necessary changes.
