New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 5.9
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)
Solution
Apply the appropriate patch according to the vendor advisory that pertains to ESX version 3.5 / 4.0.
