Multiple vulnerabilities has been found and corrected in krb5: The get_input_token function in the SPNEGO implementation in MIT Kerberos 5 1.5 through 1.6.3 allows remote attackers to cause a denial of service and possibly obtain sensitive information via a crafted length value that triggers a buffer over-read . The spnego_gss_accept_sec_context function in lib/gssapi/spnego/spnego_mech.c in MIT Kerberos 5 1.5 through 1.6.3, when SPNEGO is used, allows remote attackers to cause a denial of service via invalid ContextFlags data in the reqFlags field in a negTokenInit token . The asn1_decode_generaltime function in lib/krb5/asn.1/asn1_decode.c in the ASN.1 GeneralizedTime decoder in MIT Kerberos 5 before 1.6.4 allows remote attackers to cause a denial of service or possibly execute arbitrary code via vectors involving an invalid DER encoding that triggers a free of an uninitialized pointer . The asn1buf_imbed function in the ASN.1 decoder in MIT Kerberos 5 1.6.3, when PK-INIT is used, allows remote attackers to cause a denial of service via a crafted length value that triggers an erroneous malloc call, related to incorrect calculations with pointer arithmetic . 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.
