Important: python-twisted security update (Amazon Linux 2023)

Published Feb 17, 2023 · Updated Feb 22, 2023

Ecosystem: Amazon Linux

Summary

Package updates are available for Amazon Linux 2023 that fix the following vulnerabilities: CVE-2022-24801: A flaw was found in python-twisted. This vulnerability occurs due to the parsing of illegal constructs in the twisted.web.http module. The illegal constructs include '+/-' in the Content-Length header, '\n and \t' etc. Non-conformant parsing leads to a desync if requests pass through multiple HTTP parsers. This flaw allows a remote attacker to perform an HTTP request smuggling attack. CVE-2022-21716: An uncontrolled resource consumption flaw was found in python-twisted in the dataReceived() function. This flaw allows an unauthenticated, remote attacker to send a simple command to use all available memory and crash the server. CVE-2022-21712: A flaw was found in the twisted Python library when WebClient redirects via the RedirectAgent and BrowserLikeRedirectAgent methods. This flaw allows an attacker to take advantage of these cross-origin redirects and leak the cookie and authorization headers.
