The remote VMware ESX / ESXi host is missing a security-related patch.
It is, therefore, affected by an unspecified flaw in the Tools update functionality due to improper validation of user-supplied input. A local attacker with host operating system access can exploit this flaw to gain root privileges on the guess operating system.
