	Buffer overflow in the mac_partition function in
	fs/partitions/mac.c in the Linux kernel before allows
	local users to cause a denial of service (panic) or possibly have
	unspecified other impact via a malformed Mac OS partition table.

The fix for this has hit everything since Hardy already either via
mainline or stable updates.  Following this email is a patch for hardy
this is a minor backport of the upstream commit.

Proposing for Hardy.
