gnome-autoar regression
==========================================================================

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

- Ubuntu 21.04
- Ubuntu 20.10
- Ubuntu 20.04 LTS
- Ubuntu 18.04 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:

Ubuntu 21.04:
libgnome-autoar-0-0 0.3.1-1ubuntu0.1
