tag_insight = "Due to overzealous applied patches, the security update DSA 269-1
introduced problems in some installations, causing the hprop service
to fail.  This is corrected with the update below.

For completeness, here is the original advisory text:

A cryptographic weakness in version 4 of the Kerberos protocol allows
an attacker to use a chosen-plaintext attack to impersonate any
principal in a realm.  Additional cryptographic weaknesses in the krb4
implementation permit the use of cut-and-paste attacks to fabricate
krb4 tickets for unauthorized client principals if triple-DES keys are
used to key krb4 services.  These attacks can subvert a site's entire
Kerberos authentication infrastructure.

This version of the heimdal package changes the default behavior and
disallows cross-realm authentication for Kerberos version 4.  Because
of the fundamental nature of the problem, cross-realm authentication
in Kerberos version 4 cannot be made secure and sites should avoid its
use.  A new option (--kerberos4-cross-realm) is provided to the kdc
command to re-enable version 4 cross-realm authentication for those
sites that must use this functionality but desire the other security
fixes.

For the stable distribution (woody) these problems have been
fixed in version 0.4e-7.woody.8.

The old stable distribution (potato) is not affected by this problem,
since it isn't compiled against kerberos 4.

For the unstable distribution (sid) the original problem has been
fixed in version 0.5.2-1 and since it was a new upstream version did
not contain the problem mentioned above.

We recommend that you upgrade your heimdal packages.";
