==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 21.04
- Ubuntu 20.10
- Ubuntu 20.04 LTS

Summary:
USN-4937-1 introduced a regression in GNOME Autoar.
Software Description:
- gnome-autoar: Archive integration support for GNOME
Details:
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.

package versions:
