high Nessus Plugin ID 204858

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6928-1 advisory.

 It was discovered that the Python ssl module contained a memory race condition when handling the APIs to obtain the CA certificates and certificate store statistics. This could possibly result in applications obtaining wrong results, leading to various SSL issues. (CVE-2024-0397)

 It was discovered that the Python ipaddress module contained incorrect information about which IP address ranges were considered private or globally reachable. This could possibly result in applications applying incorrect security policies. (CVE-2024-4032)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
