USN-4733-1: GNOME Autoar vulnerability

11 February 2021

GNOME Autoar could be made to overwrite files.




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
Ubuntu 20.04
Ubuntu 18.04

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