Synopsis:	Important: krb5 security update
Issue date:	2011-02-08
CVE Names:	CVE-2011-0281 CVE-2011-0282

A NULL pointer dereference flaw was found in the way the MIT Kerberos 
KDC processed principal names that were not null terminated, when the 
KDC was configured to use an LDAP back end. A remote attacker could use 
this flaw to crash the KDC via a specially-crafted request. (CVE-2011-0282)

A denial of service flaw was found in the way the MIT Kerberos KDC
processed certain principal names when the KDC was configured to use an
LDAP back end. A remote attacker could use this flaw to cause the KDC to
hang via a specially-crafted request. (CVE-2011-0281)

After installing the updated packages, the krb5kdc daemon will be 
restarted automatically.
