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.
