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.
