USN-4937-1: GNOME Autoar vulnerability

Releases

• Ubuntu 20.10
• Ubuntu 20.04 LTS
• Ubuntu 18.04 ESM

Packages

• gnome-autoar - Archive integration support for GNOME

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.

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

• 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.
