4) Description of Vulnerability
Secunia Research has discovered a vulnerability in SAP GUI, 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
TabOne ActiveX control (sizerone.ocx) when copying tab captions. This
can be exploited to cause a heap-based buffer overflow by e.g. adding
multiple tabs via the "AddTab()" method.
Successful exploitation may allow execution of arbitrary code.
======================================================================
5) Solution
Update to the latest 7.10 PL, which sets the kill-bit for the ActiveX
control.
Users can also set the kill-bit manually by following the procedure
explained in SAP note 1092631.
