MGASA-2024-0351 - Updated python-werkzeug packages fix security vulnerability

Publication date: 09 Nov 2024
URL: https://advisories.mageia.org/MGASA-2024-0351.html
Type: security
Affected Mageia releases: 9
CVE: CVE-2024-49767

Werkzeug is a Web Server Gateway Interface web application library.
Applications using `werkzeug.formparser.MultiPartParser` corresponding
to a version of Werkzeug prior to 3.0.6 to parsing `multipart/form-data`
requests (e.g. all flask applications) are vulnerable to a relatively
simple but effective resource exhaustion (denial of service) attack. A
specifically crafted form submission request can cause the parser to
allocate and block 3 to 8 times the upload size in main memory. There is
no upper limit; a single upload at 1 Gbit/s can exhaust 32 GB of RAM in
less than 60 seconds. Werkzeug version 3.0.6 fixes this issue.
