[Florian Weimer]

This entry

CAN-2005-1766 (Heap-based buffer overflow in rtffplin.cpp in RealPlayer 10.5 ...)
	NOTE: not-for-us (RealPlayer)

is incorrenct because Helix Player is affected as well:

I will fix this entry.  Would someone browse through the CAN file to
check if there are similar mistakes, please?
