// source: https://www.securityfocus.com/bid/44989/info Multiple products from Native Instruments are prone to multiple vulnerabilities that let attackers execute arbitrary code. An attacker can exploit these issues by enticing a legitimate user to use a vulnerable application to open a file from a network share location that contains a specially crafted Dynamic Link Library (DLL) file. The issues affect the following: Guitar Rig 4 Player 4.1.1 KONTAKT 4 PLAYER 4.1.3.4125 Service Center 2.2.5 REAKTOR 5 PLAYER 5.5.1.10584 /* Native Instruments Guitar Rig 4 Player v4.1.1 Insecure Library Loading Vulnerability Vendor: Native Instruments GmbH Product web page: http://www.native-instruments.com Affected version: 4.1.1.1845 (Standalone) Summary: GUITAR RIG 4 PLAYER is the free, modular and expandable effects processor from Native Instruments, combining creative effects routing possibilities with ease-of-use and pristine sound quality. The included FACTORY SELECTION library provides one stunning Amp emulation with Matched Cabinet, plus 20 effects and sound modifiers to shape and enhance any audio signal. Desc: Guitar Rig 4 Player 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 (.nkm and .nkp) from a network share.
