-----------------------------------------------------------------
Advisory ID: SUSE-SU-2025:3227-1
Released:    Mon Sep 15 14:33:21 2025
Summary:     Security update for krb5
Type:        security
Severity:    moderate
References:  1241219,CVE-2025-3576
This update for krb5 fixes the following issues:

- CVE-2025-3576: weakness in the MD5 checksum design allows for spoofing of GSSAPI-protected messages that are using
  RC4-HMAC-MD5 (bsc#1241219).

Krb5, as a very old protocol, supported quite a number of ciphers that are not longer up to current cryptographic
standards.

To avoid problems with those, SUSE has by default now disabled those alorithms.

The following algorithms have been removed from valid krb5 enctypes:

- des3-cbc-sha1
- arcfour-hmac-md5

To reenable those algorithms, you can use allow options in `krb5.conf`:

```
[libdefaults]
allow_des3 = true
allow_rc4 = true
```


The following package changes have been done:

- krb5-1.19.2-150300.25.1 updated
