DESCRIPTION:
Luigi Auriemma has discovered two vulnerabilities in Rockwell
Automation products, which can be exploited by malicious people to
cause a DoS (Denial of Service).

1) An error in the FactoryTalk Diagnostics Receiver service
(RNADiagReceiver.exe) when processing datagrams can be exploited to
prevent processing subsequent connections via a datagram containing
more than 2000 bytes sent to UDP port 4445.

2) An input validation error in the FactoryTalk Diagnostics Receiver
service (RNADiagReceiver.exe) when processing certain datagrams can
be exploited to cause a crash via a specially crafted datagram sent
to UDP port 4445.

The vulnerabilities are confirmed in RNADiagReceiver.exe version
2.10.1.16. Other versions may also be affected.

SOLUTION:
Restrict access to trusted hosts only.
