[parted-devel] [PATCH 2/2] libparted: fix several integer overflows with dvh labels

[Brian C. Lane]

From: Ming Liu <ming.liu at windriver.com>

Integer overflows was found in libparted/labels/dvh.c, while attemptting
assign unsigned int values to int types in some places.

Defined by unsigned int instead.

* libparted/labels/dvh.h: Change int to unsigned int
