Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

Multiple vulnerabilities has been found and corrected in krb5 :

The krb5_ldap_lockout_audit function in the Key Distribution Center
(KDC) in MIT Kerberos 5 (aka krb5) 1.8 through 1.8.4 and 1.9 through
1.9.1, when the LDAP back end is used, allows remote attackers to
cause a denial of service (assertion failure and daemon exit) via
unspecified vectors, related to the locked_check_p function
(CVE-2011-1528).

The lookup_lockout_policy function in the Key Distribution Center
(KDC) in MIT Kerberos 5 (aka krb5) 1.8 through 1.8.4 and 1.9 through
1.9.1, when the db2 (aka Berkeley DB) or LDAP back end is used, allows
remote attackers to cause a denial of service (NULL pointer
dereference and daemon crash) via vectors that trigger certain
process_as_req errors (CVE-2011-1529).

The updated packages have been patched to correct these issues.

Solution :

Update the affected packages.
