HEAP Error

[Saeed]

There is an API that I need to call to fetch a VALUE (UID)

//declaration
RET_STATUS ActivateIdle(uint8_t *pabATQ = NULL,
uint8_t *pbSAK = NULL,
uint8_t *pabUID = NULL,
uint8_t *pbUIDLength = NULL);

when the API is called with no parameters (poRd700Wrapper->ActivateIdle() ) program terminates normally but when it is used with passing the Pointers , although I get to get my value that I want (UID) returned but I get a
HEAP CORRUPTION DETECTED. CRT detected that the application wrote to memory after end of heap buffer

Its been a while since I did work with pointers in C++ but from what it seems API is allocating stoarge that its not releasing upon its return;
Am i right about this ?

		uint8_t *pabATQ= new uint8_t(0);
		uint8_t *pbSAK = new uint8_t(0);
 		uint8_t *pabUID= new uint8_t(0);
		uint8_t *pbUIDLength = new uint8_t(0);


// This Call seems to be OK
//if( ( retsReturnCode = poRd700Wrapper->ActivateIdle() ) != MI_OK )
// This Call Causes the crash.
if( ( retsReturnCode = poRd700Wrapper->ActivateIdle(pabATQ,pbSAK,pabUID,pbUIDLength))!= MI_OK)	{
        delete poRd700Wrapper;
        poRd700Wrapper = NULL;
        return NULL;
    }
	if(pbUIDLength)
	{
		if(pabUID != NULL)
		{
			uint8_t i;
			for(i=0;i<*pbUIDLength;i++)
			{
			sprintf(textUID,"%s%02x ",textUID, *pabUID+i));
			}
		}
	}

	delete pabATQ;
	delete pbSAK;
 	delete pabUID;
	delete pbUIDLength;

Is there anything obvious that I don't see ?
Cheers
