Secunia Research has discovered a vulnerability in SonicWALL SSL-VPN End-Point Interrogator/Installer ActiveX Control, which can be exploited by malicious people to compromise a user's system. The vulnerability is caused by a boundary error in the "Install3rdPartyComponent()" method in the "Aventail.EPInstaller" ActiveX control when creating an absolute path name based on values in the "CabURL" and "Location" arguments. This can be exploited to cause a stack-based buffer overflow via overly long values. Successful exploitation allows execution of arbitrary code.
