The version of the remote VMware ESXi 5.5 host is prior to build 5230635. It is, therefore, affected by multiple vulnerabilities:
VMware ESXi 5.5 without patch ESXi550-201703401-SG has a Heap Buffer Overflow in SVGA. This issue may allow a guest to execute code on the host. (CVE-2017-4902)
VMware ESXi 5.5 without patch ESXi550-201703401-SG has an uninitialized stack memory usage in SVGA. This issue may allow a guest to execute code on the host. (CVE-2017-4903) Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
