ESXi 5.5 < Build 3568722 / 6.0 < Build 3568940 glibc DNS Resolver RCE (VMSA-2016-0002) (remote check)

high Nessus Plugin ID 88906
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote VMware ESXi host is affected by a remote code execution vulnerability.

Description

The remote VMware ESXi host is 5.5 prior to build 3568722 or 6.0 prior to build 3568940. It is, therefore, affected by a stack-based buffer overflow condition in the GNU C Library (glibc) DNS client-side resolver due to improper validation of user-supplied input when looking up names via the getaddrinfo() function. An attacker can exploit this to execute arbitrary code by using an attacker-controlled domain name, an attacker-controlled DNS server, or through a man-in-the-middle attack.

Solution

Apply the appropriate patch as referenced in the vendor advisory.
