Releases

• Ubuntu 20.04 LTS
• Ubuntu 18.04 ESM

Packages

• gnome-autoar - Archive integration support for GNOME

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 - 0.2.4-2ubuntu0.1
• libgnome-autoar-gtk-0-0 - 0.2.4-2ubuntu0.1

Ubuntu 20.04

Ubuntu 18.04

• libgnome-autoar-0-0 - 0.2.3-1ubuntu0.1
• libgnome-autoar-gtk-0-0 - 0.2.3-1ubuntu0.1

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