Title: Native Instruments Traktor Pro 1.2.6 Stack-based Buffer Overflow Vulnerability
Advisory ID: ZSL-2010-4977
Type: Local/Remote
Impact: System Access, DoS
Risk: (4/5)
Release Date: 20.11.2010
TRAKTOR PRO is the new benchmark in DJ software. Mix digital files on four decks, using the high-quality internal mixer or external hardware, and the best effects suite around. Fully primed for professional use, TRAKTOR PRO redefines the art of DJing.
Desc: Traktor Pro suffers from a stack buffer overflow vulnerability when parsing playlist files (.nml) 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.
