CVE-2025-49007

一、漏洞信息
 漏洞编号：[CVE-2025-49007](https://nvd.nist.gov/vuln/detail/CVE-2025-49007)
 漏洞归属组件：[rubygem-rack](https://gitee.com/src-openeuler/rubygem-rack)
 漏洞归属的版本：2.0.4,2.0.8,2.2.2,2.2.3.1,2.2.4
 CVSS V3.0分值：
  BaseScore：5.3 Medium
  Vector：CVSS：3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
 漏洞简述：
  Rack is a modular Ruby web server interface. Starting in version 3.1.0 and prior to version 3.1.16, there is a denial of service vulnerability in the Content-Disposition parsing component of Rack. This is very similar to the previous security issue CVE-2022-44571. Carefully crafted input can cause Content-Disposition header parsing in Rack to take an unexpected amount of time, possibly resulting in a denial of service attack vector. This header is used typically used in multipart parsing. Any applications that parse multipart posts using Rack (virtually all Rails applications) are impacted. Version 3.1.16 contains a patch for the vulnerability.
