CVE-2023-28119, GHSA-5mqj-xc49-246p

go/github.com/crewjam/saml

Allocation of Resources Without Limits or Throttling

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.

All versions before 0.4.13

Upgrade to version 0.4.13 or above.
