 Mandriva Linux Security Advisory                         MDVSA-2009:098
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : krb5
 Date    : April 27, 2009
 Affected: 2008.1, 2009.0, Corporate 3.0, Corporate 4.0
 _______________________________________________________________________

 Problem Description:

 Multiple vulnerabilities has been found and corrected in krb5:
 
 The get_input_token function in the SPNEGO implementation in MIT
 Kerberos 5 (aka krb5) 1.5 through 1.6.3 allows remote attackers to
 cause a denial of service (daemon crash) and possibly obtain sensitive
 information via a crafted length value that triggers a buffer over-read
 (CVE-2009-0844).
 
 The asn1_decode_generaltime function in lib/krb5/asn.1/asn1_decode.c in
 the ASN.1 GeneralizedTime decoder in MIT Kerberos 5 (aka krb5) before
 1.6.4 allows remote attackers to cause a denial of service (daemon
 crash) or possibly execute arbitrary code via vectors involving an
 invalid DER encoding that triggers a free of an uninitialized pointer
 (CVE-2009-0846).
 
 The asn1buf_imbed function in the ASN.1 decoder in MIT Kerberos 5
 (aka krb5) 1.6.3, when PK-INIT is used, allows remote attackers to
 cause a denial of service (application crash) via a crafted length
 value that triggers an erroneous malloc call, related to incorrect
 calculations with pointer arithmetic (CVE-2009-0847).
 
 The updated packages have been patched to correct these issues.

 Update:

 krb5 packages for Mandriva Linux Corporate Server 3 and 4 are not
 affected by CVE-2009-0844 and CVE-2009-0845
