CVE编号
CVE-2023-28119利用情况
暂无补丁情况
官方补丁披露时间
2023-03-23漏洞描述
The crewjam/saml go library contains a partial implementation of the SAML standard in golang. Prior to version 0.4.13, the package's use of `flate.NewReader` does not limit the size of the input. The user can pass more than 1 MB of data in the HTTP request to the processing functions, which will be decompressed server-side using the Deflate algorithm. Therefore, after repeating the same request multiple times, it is possible to achieve a reliable crash since the operating system kills the process. This issue is patched in version 0.4.13.解决建议
建议您更新当前系统或软件至最新版，完成漏洞的修复。
