====================================================================== 4) Description of Vulnerability

Secunia Research has discovered a vulnerability in NCTAudioStudio, NCTAudioEditor, and NCTDialogicVoice, 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 (NCTAudioFile2.dll) 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.
