EulerOS 2.0 SP3 : python-ipaddress (EulerOS-SA-2021-1115)

medium Nessus Plugin ID 145170

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the python-ipaddress package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

 - 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 Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected python-ipaddress package.
