Ubuntu Security Notice USN-4457-1
August 12, 2020

software-properties vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS

Summary:

Software Properties could be made to manipulate the display.

Software Description:
- software-properties: manage the repositories that you install software from

Details:

Jason A. Donenfeld discovered that Software Properties incorrectly filtered
certain escape sequences when displaying PPA descriptions. If a user were
tricked into adding an arbitrary PPA, a remote attacker could possibly
manipulate the screen.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 20.04 LTS:
  python3-software-properties     0.98.9.2
  software-properties-common      0.98.9.2

Ubuntu 18.04 LTS:
  python3-software-properties     0.96.24.32.14
  software-properties-common      0.96.24.32.14

Ubuntu 16.04 LTS:
  python-software-properties      0.96.20.10
  python3-software-properties     0.96.20.10
  software-properties-common      0.96.20.10

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