Calls that checked one byte of a game's buffer and then wrote or read the
whole thing, or trusted a negative length:
- sceNetEtherNtostr/Strton, the apctl BSS descriptor calls, GetState and
sceNetGetDropRate.
- sceNpAuthGetTicket wrote its whole ticket whatever the length; it's
now built locally and written once the buffer is known to hold it.
sceNpAuthGetTicketParam checked its limits after copying, and walked
ticket params past the ticket's end.
- sceNp2's communication ID and passphrase, a negative maxServerIds, and
an unchecked unknown1Ptr.
- sceParseUri's work area and scheme string, sceParseHttp's negative
header length and value address, and ReadVariableSizedStruct's size.
- sceKernelCreateLwMutex initialized the work area without checking it
at all, and the other LwMutex calls checked one byte of it.
- sceNetAdhocctlGetScanInfo cleared the length the game gave, of a
buffer checked by one byte (or any length, negative ones included).
Also: a game mode join inserted at begin() + 1 into a possibly empty
list of players.
