Mandriva Linux Security Advisory MDVSA-2008:071
http://www.mandriva.com/security/
_______________________________________________________________________

Package : krb5
Date : March 19, 2008
Affected: Corporate 3.0, Multi Network Firewall 2.0
_______________________________________________________________________

Problem Description:

A flaw was discovered in how the Kerberos krb5kdc handled Kerberos v4
protocol packets. An unauthenticated remote attacker could use this
flaw to crash the krb5kdc daemon, disclose portions of its memory,
or possibly %execute arbitrary code using malformed or truncated
Kerberos v4 protocol requests (CVE-2008-0062, CVE-2008-0063).

This issue only affects krb5kdc when it has Kerberos v4 protocol
compatibility enabled, which is a compiled-in default in all
Kerberos versions that Mandriva Linux ships prior to Mandriva
Linux 2008.0. Kerberos v4 protocol support can be disabled by
adding v4_mode=none (without quotes) to the [kdcdefaults] section
of /etc/kerberos/krb5kdc/kdc.conf.

The updated packages have been patched to correct these issues.
