 Mandriva Linux Security Advisory                         MDVSA-2011:159
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : krb5
 Date    : October 22, 2011
 Affected: 2011.
 _______________________________________________________________________

 Problem Description:

 Multiple vulnerabilities has been found and corrected in krb5:
 
 The kdb_ldap plugin in the Key Distribution Center (KDC) in
 MIT Kerberos 5 (aka krb5) 1.9 through 1.9.1, when the LDAP
 back end is used, allows remote attackers to cause a denial of
 service (NULL pointer dereference and daemon crash) via a kinit
 operation with incorrect string case for the realm, related to the
 is_principal_in_realm, krb5_set_error_message, krb5_ldap_get_principal,
 and process_as_req functions (CVE-2011-1527).
 
 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.
