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

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.
