Microsoft Security Bulletin MS11-083 and Forefront TMG 2010

November 12, 2011 2 comments

Included in the November Microsoft security bulletin release was security update MS11-083 (KB2588516) that addresses a critical vulnerability in TCP/IP that could allow remote code execution. Forefront TMG 2010 firewalls are protected from this vulnerability, as the firewall engine’s kernel mode driver processes packets even before the operating system sees them. More information about how the Forefront TMG 2010 firewall engine and service work can be found here [this document is for ISA, but TMG is similar]. Although the underlying operating system’s TCP/IP networking stack is protected by the Forefront TMG firewall engine driver, TMG administrators are still strongly encouraged to install the MS11-083 update as soon as possible.
