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.
