CVE-2024-49767 is fixed in 4 products on 1 platform, first by python3-werkzeug 2.0.2+dfsg1-1ubuntu0.22.04.3, released October 25, 2024. It is not reported as exploited. Patch Radar priority: High.
Werkzeug is a Web Server Gateway Interface web application library.Applications using `werkzeug.formparser.MultiPartParser` corresponding to aversion of Werkzeug prior to 3.0.6 to parse `multipart/form-data` requests(e.g. all flask applications) are vulnerable to a relatively simple buteffective resource exhaustion (denial of service) attack. A specificallycrafted form submission request can cause the parser to allocate and block3 to 8 times the upload size in main memory. There is no upper limit; asingle upload at 1 Gbit/s can exhaust 32 GB of RAM in less than 60 seconds.Werkzeug version 3.0.6 fixes this issue.
