tag_insight = "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 spnego_gss_accept_sec_context function in
lib/gssapi/spnego/spnego_mech.c in MIT Kerberos 5 (aka krb5) 1.5
through 1.6.3, when SPNEGO is used, allows remote attackers to cause
a denial of service (NULL pointer dereference and daemon crash) via
invalid ContextFlags data in the reqFlags field in a negTokenInit token
(CVE-2009-0845).

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:

Packages for 2008.0 are being provided due to extended support for
Corporate products.

Affected: 2008.0";
