Advisory ID: ZSL-2010-4974
Type: Local/Remote

Summary
REAKTOR 5 PLAYER is your free entry point to the award-winning and avant-garde audio world of REAKTOR 5 - the super-powerful modular sound studio that made Native Instruments famous.
Description
Reaktor 5 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 (.ens, .ism, .map, .mdl, .ntf, .rcc, .rcm, .rkplr and .ssf) from a network share.
