4) Description of Vulnerability
Secunia Research has discovered a vulnerability in two RMBSoft
products, which can be exploited by malicious people to compromise a
user's system.
The vulnerability is caused due to a boundary error in the
NCTAudioFile2.AudioFile ActiveX control when handling the
"SetFormatLikeSample()" method. This can be exploited to cause a
stack-based buffer overflow by passing an overly long string (about
4124 bytes) as argument to the affected method.
Successful exploitation allows execution of arbitrary code when a user
e.g. visits a malicious website.
======================================================================
5) Solution
Set the kill-bit for the affected ActiveX control.
Use another product.
======================================================================
6) Time Table
