DESCRIPTION:
Secunia Research has discovered a vulnerability in TSC2 Help Desk ,
which can be exploited by malicious people to potentially compromise
a user's system.
The vulnerability is caused due to a boundary error in the included
CTab ActiveX control (c1sizer.ocx) when copying tab captions. This
can be exploited to cause a heap-based buffer overflow by e.g. adding
tabs with overly long captions via the "AddTab()" method.
Successful exploitation may allow execution of arbitrary code.
The vulnerability is confirmed in version 4.1.8. Other versions may
also be affected.
SOLUTION:
Set the kill-bit for the affected ActiveX control.
