Releases

Packages

  • python-apt - Python interface to libapt-pkg

Details

USN-4668-1 fixed vulnerabilities in python-apt. That update caused a
regression by removing information describing the Ubuntu 20.10 release from
the Ubuntu templates. This update fixes the problem by restoring this
information.

We apologize for the inconvenience.

Original advisory details:

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

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