DESCRIPTION:
Secunia Research has discovered a vulnerability in RSLinx, which can
be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error in the OPC
Automation ActiveX control ("RsiOPCAuto.OPCServer") when creating
debug strings. This can be exploited to cause a stack-based buffer
overflow via an overly long string passed e.g. in the "ProgID"
parameter to the "Connect()" method.

Successful exploitation allows execution of arbitrary code.

The vulnerability is reported in versions prior to 2.55 (confirmed in
2.3.1 Build 10 RsiOPCAuto.dll version 1.1.8.0).

SOLUTION:
Update to version 2.55 or apply patch (scheduled for July 2011).
