Summary
generated automatically from NVD dataVMware vCenter Server, vCenter Server Appliance, ESXi and ESX contain a flaw in their implementation of the Network File Copy (NFC) protocol. A man-in-the-middle attacker who modifies the client-server data stream can cause memory corruption, leading to arbitrary code execution or a denial of service. The issue affects vCenter Server 4.0 before Update 4b, 5.0 before Update 2 and 5.1 before 5.1.0b, plus ESXi 3.5 through 5.1 and ESX 3.5 through 4.1. It is rated 7.6 (HIGH) under CVSS v2.0.
