USN-4668-1: python-apt vulnerability

9 December 2020

python-apt could be made to crash if it opened a specially crafted file.




Kevin Backhouse discovered that python-apt incorrectly handled resources. A
local attacker could possibly use this issue to cause python-apt to consume
resources, leading to a denial of service.

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
Ubuntu 16.04

In general, a standard system update will make all the necessary changes.
