Description

The remote Windows host is missing a security update. It is, therefore, affected by an elevation of privilege vulnerability in the Pragmatic General Multicast (PGM) protocol, installed with the MSMQ service, due to a race condition that can result in references being made to already freed memory. An local attacker can exploit this, via a specially crafted application, to gain elevated privileges on the affected host.
