19 June 2019

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.
