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.
