Integer overflows were found in libparted/labels/dvh.c, while attemptting
to assign unsigned int values to int types in some places. These overflows
only can be observed on BE platforms like MIPS, when the "WORDS_BIGENDIAN"
macro is defined in parted.
Defined by unsigned int instead.

Did you send it upstream? Jim or I can review it.

Yes, I sent it to bug-parted@gnu.org a week ago, but didn't get any
feedback, the mail link:
http://lists.gnu.org/archive/html/bug-parted/2013-02/msg00004.html
That's great if you can review it!
the best,
thank you
