 Mandriva Linux Security Advisory                         MDVSA-2013:158
 http://www.mandriva.com/en/support/security/
 _______________________________________________________________________

 Package : krb5
 Date    : April 30, 2013
 Affected: Business Server 1.0
 _______________________________________________________________________

 Problem Description:

 A vulnerability has been discovered and corrected in krb5:
 
 The prep_reprocess_req function in do_tgs_req.c in the Key Distribution
 Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.10.5 does not
 properly perform service-principal realm referral, which allows
 remote authenticated users to cause a denial of service (NULL
 pointer dereference and daemon crash) via a crafted TGS-REQ request
 (CVE-2013-1416).
 
 The updated packages have been patched to correct this issue.
