Infinite Recursion It is possible to design a FRAMESET that recurses infinitely, stacking the same FRAMESET inside itself until a machine runs out of memory. Consider this example: <FRAMESET rows="50%,50%"> <FRAME src="parent_url"> <FRAME> </FRAMESET> Infinite recursion is prevented. Any frame that attempts to assign as its SRC a URL used by any of its ancestors is treated as if it has no SRC URL at all (basically a blank frame). This doesn't prevent all malicious documents, but it eliminates a troublesome class of them. |
