USN-4973-2: Python vulnerability
4 October 2021
Python could allow unintended access to network services.
Releases
Packages
- python3.8 - An interactive high-level object-oriented language
Details
USN-4973-1 fixed this vulnerability previously, but it was re-introduced
in python3.8 in focal because of the SRU in LP: #1928057. This update fixes
the problem.
Original advisory details:
It was discovered that the Python stdlib ipaddress API incorrectly handled
octal strings. A remote attacker could possibly use this issue to perform a
wide variety of attacks, including bypassing certain access restrictions.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 20.04
In general, a standard system update will make all the necessary changes.
