DESCRIPTION:
Markot has discovered a vulnerability in various MemDB products,
which can be exploited by malicious people to potentially compromise
a vulnerable system.

The vulnerability is caused due to a boundary error in the embedded
web server when parsing the HTTP "Host" header and can be exploited
to cause a stack-based buffer overflow.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is confirmed in the following products:
* Memory Database System 1.02
* Online Survey System version 2006 1.0
* MemCompany 1.0

Other products and versions may also be affected.

SOLUTION:
Restrict access to the web service to trusted hosts only (e.g. via
network access control lists).
