|Bugzilla:||668726: CVE-2011-0282 krb5: KDC crash when using LDAP backend caused by a special principal name (MITKRB5-SA-2011-002)|
The MITRE CVE dictionary describes this issue as:
The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.6.x through 1.9, when an LDAP backend is used, allows remote attackers to cause a denial of service (NULL pointer dereference or buffer over-read, and daemon crash) via a crafted principal name.
This issue did not affect the versions of krb5 as shipped with Red Hat Enterprise Linux 3 or 4 as they did not include support for the LDAP backend.
