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 is different from CVSS.

VPR Score: 8.9

Synopsis

The remote VMware ESX host is missing a security-related patch.

Description

The remote VMware ESX host is missing a security-related patch. It is, therefore, affected by a memory allocation issue in the Linux 64-bit kernel due to a failure by the compat_alloc_user_space() function to properly allocate the user space memory required for the 32-bit compatibility layer. A local attacker can exploit this to gain elevated privileges by leveraging the ability of the compat_mc_getsockopt() function to control a certain length value.

Solution

Apply the appropriate patch as referenced in the vendor advisory that pertains to ESX version 4.0 / 4.1.
