| 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]]
