SOFTWARE:

DESCRIPTION:
A vulnerability has been reported in the NOS Microsystems getPlus
ActiveX control, which can be exploited by malicious people to
compromise a user's system.

The vulnerability is caused due to an unspecified error within gp.ocx
when processing installation files. This can be exploited to cause a
stack-based buffer overflow by e.g. tricking a user into visiting a
malicious website.

Successful exploitation allows the execution of arbitrary code, but
may require that the attacker can place files on the domain or
subdomain of a product using the download manager.

The vulnerability is reported in gp.ocx version 1.2.2.50. Other
versions may also be affected.

SOLUTION:
Set the kill-bit for the affected ActiveX control.
