Ubuntu Security Notice USN-7219-1
January 20, 2025

python3.12 vulnerability
==========================================================================

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

- Ubuntu 24.10
- Ubuntu 24.04 LTS

Summary:

Python could be made to consume resources if it received specially crafted
network traffic.

Software Description:
- python3.12: An interactive high-level object-oriented language

Details:

It was discovered that Python incorrectly handled asyncio write buffers. A
remote attacker could possibly use this issue to cause Python to consume
memory, leading to a denial of service.

Update instructions:

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

Ubuntu 24.10
   python3.12                      3.12.7-1ubuntu1.1
   python3.12-minimal              3.12.7-1ubuntu1.1

Ubuntu 24.04 LTS
   python3.12                      3.12.3-1ubuntu0.4
   python3.12-minimal              3.12.3-1ubuntu0.4

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