DESCRIPTION:
m1k3 has discovered a vulnerability in Winlog, which can be exploited
by malicious people to compromise a vulnerable system.

The vulnerability is caused due to an error in RunTime.exe when
processing packets and can be exploited to cause a stack-based buffer
overflow via a specially crafted packet sent to TCP port 46824.

Successful exploitation allows execution of arbitrary code, but
requires a project to be configured for TCP server mode (not by
default).

The vulnerability is confirmed in version 2.07.14. Other versions may
also be affected.

SOLUTION:
Restrict access to trusted hosts only.
