Vulnerability Assessment Details

[DSA266] DSA-266-1 krb5

Vulnerability Assessment Summary
DSA-266-1 krb5

Detailed Explanation for this Vulnerability Assessment

Several vulnerabilities have been discovered in krb5, an
implementation of MIT Kerberos.
Kerberos version 5 does not contain this cryptographic
vulnerability. Sites are not vulnerable if they have Kerberos v4
completely disabled, including the disabling of any krb5 to krb4
translation services.

This version of the krb5 package changes the default behavior and
dispermits 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 (-X) is provided to the krb5kdc and krb524d
commands 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) this problem has been
fixed in version 1.2.4-5woody4.
The old stable distribution (potato) does not contain krb5 packages.
For the unstable distribution (sid) this problem will be fixed soon.
We recommend that you upgrade your krb5 package.
