Description: LeadTools MultiMedia 15 - 'Ltmm15.dll' ActiveX Control Stack Buffer Overflow
Type: remote
Platform: windows
Date: 2007-05-17
Author: shinnai

Exploit:
source: https://www.securityfocus.com/bid/24035/info

LEADTOOLS Multimedia is prone to a stack-based buffer-overflow vulnerability because the software fails to adequately check boundaries on data supplied to an ActiveX control method.

An attacker can exploit this issue to execute arbitrary code in the context of a user running the application. Failed attempts will likely result in denial-of-service conditions.

LEADTOOLS Multimedia 15 is vulnerable; other versions may also be affected.

NOTE: The 'Ltmm15.dll' ActiveX control is included in Digital Music Mentor 2.6.0.4. Other applications may also include the ActiveX control.
