There are three identified vulnerabilities in the part of RPCSS
Service that deals with RPC messages for DCOM activation- two
that could allow arbitrary code execution and one that could
result in a denial of service. The flaws result from incorrect
handling of malformed messages. These particular vulnerabilities
affect the Distributed Component Object Model (DCOM) interface
within the RPCSS Service. This interface handles DCOM object
activation requests that are sent from one machine to another.
An attacker who successfully exploited these vulnerabilities
could be able to run code with Local System privileges on an
affected system, or could cause the RPCSS Service to fail. The
attacker could then be able to take any action on the system,
including installing programs, viewing, changing or deleting
data, or creating new accounts with full privileges.
To exploit these vulnerabilities, an attacker could create a
program to send a malformed RPC message to a vulnerable system
targeting the RPCSS Service.
