CVE-2024-49767

一、漏洞信息
 漏洞编号：[CVE-2024-49767](https://nvd.nist.gov/vuln/detail/CVE-2024-49767)
 漏洞归属组件：[python-werkzeug](https://gitee.com/src-openeuler/python-werkzeug)
 漏洞归属的版本：0.14.1,1.0.1,2.0.3,2.2.2,2.2.3
 CVSS V3.0分值：
  BaseScore：7.5 High
  Vector：CVSS：3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
 漏洞简述：
  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 parse `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.
