Summary
Red Hat Security Advisory: Red Hat OpenStack Platform 17.1 (python-werkzeug) security update
Notes
Topic
An update for python-werkzeug is now available for Red Hat OpenStack
Platform 17.1 (Wallaby).
Red Hat Product Security has rated this update as having a security impact
of Moderate. 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.
Details
Werkzeug is a WSGI utility module. It includes a debugger, request and response objects, HTTP utilities to handle entity tags, cache control headers, HTTP dates, cookie handling, file uploads, a URL routing system and a numerous community contributed add-on modules.
Werkzeug is unicode aware and does not enforce a specific template engine, database adapter or a specific way of handling requests. It is useful for end user applications, such as blogs, wikis, and bulletin boards, that need to operate in a wide variety of server environments.
Security Fix(es):
* high resource consumption leading to denial of service (CVE-2023-46136)
For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page listed in the References section.

"text": "The vulnerability found in python-werkzeug, which lets attackers carry out denial of service attacks by using carefully crafted multipart data, is considered a moderate issue because it could affect system resources and availability. When this vulnerability is exploited, it can cause the CPU to work excessively hard because the parsing mechanism keeps adding data chunks to an internal buffer without checking boundaries properly. This can result in legitimate requests being delayed or denied as worker processes get overloaded, affecting how well the web application performs and responds. While this problem doesn\u2019t directly compromise data integrity or confidentiality, exploiting it can disrupt the availability of the service, which is why it\u2019s seen as a moderate issue.",
