| 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. In [[3.0.0]], sending out of range indexes causes error code 0x60A to be returned. | | 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.
