 Mandriva Linux Security Advisory                         MDVSA-2013:157
 http://www.mandriva.com/en/support/security/
 _______________________________________________________________________

 Package : krb5
 Date    : April 30, 2013
 Affected: Enterprise Server 5.0
 _______________________________________________________________________

 Problem Description:

 Multiple vulnerabilities has been discovered and corrected in krb5:
 
 The pkinit_check_kdc_pkid function in
 plugins/preauth/pkinit/pkinit_crypto_openssl.c in the PKINIT
 implementation in the Key Distribution Center (KDC) in MIT Kerberos
 5 (aka krb5) before 1.10.4 and 1.11.x before 1.11.1 does not
 properly handle errors during extraction of fields from an X.509
 certificate, which allows remote attackers to cause a denial of
 service (NULL pointer dereference and daemon crash) via a malformed
 KRB5_PADATA_PK_AS_REQ AS-REQ request (CVE-2013-1415).
 
 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 these issues.
