DESCRIPTION:
Core Security Technologies has reported a vulnerability in Invensys

cause a DoS (Denial of Service).

The vulnerability is caused due to an error within the Wonderware
SuiteLink Service (slssvc.exe) when handling Registration packets.
This can be exploited to cause the service to crash via a specially
crafted Registration packet containing an overly large length field
sent to default port 5413/TCP.

The vulnerability is reported in WonderWare InTouch 8.0. Other
versions and products with WonderWare SuiteLink versions prior to 2.0
Patch 01 may also be affected.
