Amazon Linux 2 : python-ipaddress (ALAS-2023-2174)

medium Nessus Plugin ID 178817

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of python-ipaddress installed on the remote host is prior to 1.0.16-2. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2174 advisory.

 - Lib/ipaddress.py in Python through 3.8.3 improperly computes hash values in the IPv4Interface and IPv6Interface classes, which might allow a remote attacker to cause a denial of service if an application is affected by the performance of a dictionary containing IPv4Interface or IPv6Interface objects, and this attacker can cause many dictionary entries to be created. This is fixed in: v3.5.10, v3.5.10rc1; v3.6.12;
 v3.7.9; v3.8.4, v3.8.4rc1, v3.8.5, v3.8.6, v3.8.6rc1; v3.9.0, v3.9.0b4, v3.9.0b5, v3.9.0rc1, v3.9.0rc2.
 (CVE-2020-14422)

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

Solution

Run 'yum update python-ipaddress' to update your system.
