The remote VMware ESXi host is version 5.1 prior to build 3021178. It is, therefore, affected by a remote code execution vulnerability due to a double-free error in the SLPDProcessMessage() function in OpenSLP. An unauthenticated, remote attacker can exploit this, via a crafted package, to execute arbitrary code or cause a denial of service condition.
