DESCRIPTION:
Luigi Auriemma has discovered a vulnerability in TwinCAT, which can
be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to an error in the TCatScopeView.exe
utility when processing Scope View files. This can be exploited to
cause a heap-based buffer overflow via a specially crafted SVW file.

Successful exploitation may allow execution of arbitrary code, but
requires tricking a user into opening a malicious file.

The vulnerability is confirmed in TCatScopeView.exe version 2.9.0.226
included in TwinCAT version 2.11 R2 Build 2038. Other versions may
also be affected.

SOLUTION:
Do not open files from untrusted sources.
