USN-5713-1: Python vulnerability

Releases

• Ubuntu 22.10
• Ubuntu 22.04 LTS

Packages

• python3.10 - An interactive high-level object-oriented language

Details

Devin Jeanpierre discovered that Python incorrectly handled sockets when
the multiprocessing module was being used. A local attacker could possibly
use this issue to execute arbitrary code and escalate privileges.

Update instructions

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

Ubuntu 22.10

• python3.10 - 3.10.7-1ubuntu0.1
• python3.10-minimal - 3.10.7-1ubuntu0.1

Ubuntu 22.04

• python3.10 - 3.10.6-1~22.04.1
• python3.10-minimal - 3.10.6-1~22.04.1

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