		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">Twisted is an event-based framework for internet applications, supporting Python 2.7 and Python 3.5+. It includes modules for many different purposes, including the following:

Security Fix(es):

Twisted is an event-based framework for internet applications. Started with version 0.9.4, when the host header does not match a configured host `twisted.web.vhost.NameVirtualHost` will return a `NoResource` resource which renders the Host header unescaped into the 404 response allowing HTML and script injection. In practice this should be very difficult to exploit as being able to modify the Host header of a normal HTTP request implies that one is already in a privileged position. This issue was fixed in version 22.10.0rc1. There are no known workarounds.(CVE-2022-39348)</Note>
		<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for python-twisted is now available for openEuler-22.03-LTS-SP2.

openEuler Security has rated this update as having a security impact of medium. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.</Note>
