4) Description of Vulnerability

Secunia Research has discovered a vulnerability in ComponentOne SizerOne, which can be exploited by malicious people to potentially compromise a user's system.

The vulnerability is caused by a boundary error in the included Tab 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.



5) Solution

Update to version 8.0.20081.142 of the ActiveX control.
