System applications

Summary	Description	Fixed in version	Last version this flaw was checked for	Timeframe this was discovered	Discovered by
3DS System Settings DS profile string stack-smash	Too long or corrupted strings (01Ah 2 Nickname length in characters 050h 2 Message length in characters) in the NVRAM DS user settings (System Settings->Other Settings->Profile->Nintendo DS Profile) cause it to crash in 3DS-mode due to a stack-smash. The DSi is not vulnerable to this, DSi launcher(menu) and DSi System Settings will reset the NVRAM user-settings if the length field values are too long(same result as when the CRCs are invalid). TWL_FIRM also resets the NVRAM user-settings when the string-length(s) are too long.	7.0.0-13	7.0.0-13	2012	Ichfly
