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.Description
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.Vendor
