Hi,

The following vulnerability was published for golang-github-crewjam-saml.
Strictly speaking might be disputed if it is RC level, but would be
good to have it fixed in bookworm before the release.

CVE-2023-28119[0]:
| 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
