OOB Read in NS system module (pl:utoohax, pl:utonium, maybe other names)	Prior to 3.0.0, pl:u (Shared Font services implemented in the NS sysmodule) service commands 1,2,3 took in a signed 32-bit index and returned that index of an array but did not check that index at all. This allowed for an arbitrary read within a 34-bit range (33-bit signed) from pl:u .bss	Dumping pl:u (part of the the NS module)'s virtual memory (including code); obtaining base addresses for NS module .text (thus defeating ASLR)	3.0.0	3.0.0	April 2017	On exploit's fix in 3.0.0	qlutoo, Reswitched team (independently)
