Name: mit-krb5
CVEs: CVE-2025-3576
CVSSs: 5.9
Action Needed: TBD

Summary: A vulnerability in the MIT Kerberos implementation allows GSSAPI-protected messages using RC4-HMAC-MD5 to be spoofed due to weaknesses in the MD5 checksum design. If RC4 is preferred over stronger encryption types, an attacker could exploit MD5 collisions to forge message integrity codes. This may lead to unauthorized message tampering.

I think this one can be closed. The Debian tracker entry for the CVE-2025-3576 mentions two commits that fix the issue:

• krb5/krb5@1b57a4d
• krb5/krb5@2cbd847

Both of the commits are there since 1.21-beta1 and we are on 1.21.3 since probably 1st of July, 2024, so we were not affected since this issue was created.
