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.
