1.60 +Test rogue plugin trying to override a ROM based plugin by
1.61 +duplicating the legitimate DLL's implementation UID (different
1.62 +interface UID so that ECOM not treat it as an update).
1.63 +
1.64 +@SYMTestCaseID SYSLIB-ECOM-CIT-3161
1.65 +@SYMTestCaseDesc Copy a rogue plugin to C drive. This plugin duplicates the
1.66 + implementation UID of a built-in dll. Test if the rogue
1.67 + plugin will over shadow the built-in dll.
1.68 +@SYMTestPriority High
1.69 +@SYMTestActions 1. copy the rsc and dll of the rogue plugin to C:
1.70 + 2. Use the CreateImplementation API which does not specify
1.71 + the i/f UID to instantiate the built-in implementation.
1.72 + Test the instance works normally.
1.73 + 3. Repeat 2 but instantiate the pointer as the rogue plugin
1.74 + class. Pass NULL as the initialising param in the call
1.75 + to CreateImplementationL. Because the actual plugin returned by
1.76 + ECOM needs this initParam, KERN-EXEC 3 panic occurs.
1.77 +@SYMTestExpectedResults The test must not fail.
