Ubuntu Security Notice USN-4937-1
May 06, 2021

gnome-autoar vulnerability

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

- Ubuntu 20.10
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS


GNOME Autoar could be made to overwrite files.

Software Description:
- gnome-autoar: Archive integration support for GNOME


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 20.10:
  libgnome-autoar-0-0             0.2.4-2ubuntu0.3
  libgnome-autoar-gtk-0-0         0.2.4-2ubuntu0.3

Ubuntu 20.04 LTS:
  libgnome-autoar-0-0             0.2.3-2ubuntu0.3
  libgnome-autoar-gtk-0-0         0.2.3-2ubuntu0.3

Ubuntu 18.04 LTS:
  libgnome-autoar-0-0             0.2.3-1ubuntu0.3
  libgnome-autoar-gtk-0-0         0.2.3-1ubuntu0.3

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