USN-4937-2: GNOME Autoar regression

07 June 2021

USN-4937-1 introduced a regression in GNOME Autoar.




USN-4937-1 fixed a vulnerability in GNOME Autoar. The update caused a
regression when extracting certain archives. This update fixes the problem.

Original advisory details:

Ondrej Holy discovered that GNOME Autoar could extract files outside of the
intended directory. If a user were tricked into extracting a specially
crafted archive, a remote attacker could create files in arbitrary
locations, possibly leading to code execution.

Update instructions

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

Ubuntu 21.04
Ubuntu 20.10
Ubuntu 20.04
Ubuntu 18.04

After a standard system update you need to restart your session to make all
the necessary changes.
