EulerOS 2.0 SP5 : python (EulerOS-SA-2022-1911)

medium Nessus Plugin ID 162337

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the python packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - A flaw was found in Python, specifically in the FTP (File Transfer Protocol) client library in PASV (passive) mode. The issue is how the FTP client trusts the host from the PASV response by default. This flaw allows an attacker to set up a malicious FTP server that can trick FTP clients into connecting back to a given IP address and port. This vulnerability could lead to FTP client scanning ports, which otherwise would not have been possible. (CVE-2021-4189)

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 packages.
