Description:
rgod has discovered a vulnerability in the eCentrex VOIP Client Component ActiveX control, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error within the eCentrex SIP UA Com Module (e800) (euacom.dll) when handling an overly long argument passed to the "ReInit()" method of the eCentrex VOIP Client Component ActiveX control (uacomx.ocx). This can be exploited to cause a stack-based buffer overflow and allows execution of arbitrary code.
The vulnerability is confirmed in eCentrex VOIP Client Component version 2.0.1.0 in combination with the eCentrex SIP UA Com Module (e800) version 2.1.1.1. Other versions may also be affected.
Solution:
Set the kill-bit for the affected ActiveX control.
