Topic

An update for python-werkzeug is now available for Red Hat OpenStack
Platform 17.0 (Wallaby).

Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available for each vulnerability
from the CVE link(s) in the References section.

Description

Werkzeug ======== Werkzeug started as simple collection of various
utilities for WSGI applications and has become one of the most advanced
WSGI utility modules. It includes a powerful debugger, full featured
request and response objects, HTTP utilities to handle entity tags, cache
control headers, HTTP dates, cookie handling, file uploads, a powerful URL
routing system and a bunch of community contributed addon modules. Werkzeug
is unicode aware and doesn't enforce a specific template engine, database
adapter or anything else. It doesn't even enforce a specific way of
handling requests and leaves all that up to the developer. It's most useful
for end user applications which should work on as many server environments
as possible (such as blogs, wikis, bulletin boards, etc.).

Security Fix(es):

• high resource usage when parsing multipart form data with many fields

(CVE-2023-25577)
