The remote VMware ESX / ESXi host is affected by a remote code execution vulnerability in the vSphere Client versions 4.0 / 4.1 due to improper validation of updates to client files. An unauthenticated, remote attacker can exploit this, via a malicious link, to download and execute arbitrary code from an untrusted URI.
