    Is this bug of password security in Acrobat 9?

      If you set password to "abcde" you can release it by input just "mz".

       

      Or when longer password like "ABC-123456." then just input "x" to unsecure it.

       

      I test on Acrobat 9.3.4.

       

      If so, it is easy to unsecure all of secured pdf.
