Synopsis :

The remote host is missing a security-related patch.

Description :

The remote VMware ESX host is missing a security-related patch. It is,
therefore, affected by multiple vulnerabilities :

- An out-of-bounds read error exists in the MIT Kerberos
SPNEGO implementation in the get_input_token() function.
A remote attacker can exploit this, via a crafted
length value, to cause a denial of service or to obtain
access to sensitive information. (CVE-2009-0844)

- A NULL pointer dereference flaw exists in MIT Kerberos
in the spnego_gss_accept_sec_context() function when
SPNEGO is used. A remote attacker can exploit this, via
invalid ContextFlags data in the 'reqFlags' field within
a 'negTokenInit' token, to cause a denial of service.
(CVE-2009-0845)

- A flaw exists in the MIT Kerberos ASN.1 GeneralizedTime
decoder in the asn1_decode_generaltime() function. A
remote attacker can exploit this, via vectors involving
invalid DER encoding, to free an uninitialized pointer,
resulting in a denial of service or the execution of
arbitrary code. (CVE-2009-0846)
