high Nessus Plugin ID 161026

Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:1821 advisory.

 - python: urllib: Regular expression DoS in AbstractBasicAuthHandler (CVE-2021-3733)

 - A flaw was found in python. An improperly handled HTTP response in the HTTP client code of python may allow a remote attacker, who controls the HTTP server, to make the client script enter an infinite loop, consuming CPU time. The highest threat from this vulnerability is to system availability. (CVE-2021-3737)

 - python: ftplib should not use the host from the PASV response (CVE-2021-4189)

 - python-lxml: HTML Cleaner allows crafted and SVG embedded scripts to pass through (CVE-2021-43818)

 - python: urllib.parse does not sanitize URLs containing ASCII newline and tabs (CVE-2022-0391)

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.
