SECURITY PATCH: import una 131229 fix2
Import una 131229 fix 2.1
Merge branch 'una-orig' into asuha

Revert my patch for remote controlable vulnerability
  because I don't test the code anyway.

wget remote operation bug was partly disabled.
even no arguments probably being able to be passed, however,
  there were a little risk for invasion.
fix2.1 code will patch this risk at all.

I think mr.una intended invoke-risk for resetEXmem.php,
  but don't for /bin/echo
  so I reported this bug for mr.una;-) thanks for rapid patch
