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 NS .bss. In 3.0.0, sending out of range indexes causes error code 0x60A to be returned.	Dumping full NS .text, .rodata and .data, infoleak, etc	3.0.0	3.0.0	April 2017	On exploit's fix in 3.0.0	qlutoo, Reswitched team (independently)
Unchecked domain ID in common IPC code	Prior to 2.0.0, object IDs in domain messages are not bounds checked. This out-of-bounds read could be exploited to brute-force ASLR and get PC control in some services that support domain messages.		2.0.0
