Loader

• ldr:pm->CreateProcess() now performs additional validation on the NPDM header.
  • When the title id is one of certain hardcoded titles, Loader now validates that the version field at NPDM header is non-zero. This prevents selectively downgrading those titles to versions vulnerable to known exploits.
  • The titles checked are:
    • settings
    • bus
    • audio
    • nvservices
    • ns
    • ssl
    • es
    • creport
    • ro
