Title
USN-755-1 -- krb5 vulnerabilities
Description
Multiple flaws were discovered in the Kerberos GSS-API and ASN.1 routines that did not correctly handle certain requests. An unauthenticated remote attacker could send specially crafted traffic to crash services using the Kerberos library, leading to a denial of service.

Reference:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0847
Comment
: 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.

Comment
: 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.
