gnome-autoar regression

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

- Ubuntu 20.10
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS


USN-4733-1 introduced a regression in GNOME Autoar.

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


USN-4733-1 fixed a vulnerability in GNOME Autoar. The upstream fix
introduced a regression when extracting archives containing directories.
This update fixes the problem.

Original advisory details:

 Yiğit Can Yılmaz 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             0.2.4-2ubuntu0.2
  libgnome-autoar-gtk-0-0         0.2.4-2ubuntu0.2

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

Ubuntu 18.04 LTS:
  libgnome-autoar-0-0             0.2.3-1ubuntu0.2
  libgnome-autoar-gtk-0-0         0.2.3-1ubuntu0.2

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