[Bug 789928] [NEW] blkid: HFS+ label can't be found when block offsets exceed UINT32_MAX

[Dave Vasilevsky]

Public bug reported:

Binary package hint: util-linux

libblkid isn't careful about avoiding integer overflows. If parts of the
HFS catalog file have block offsets of more than UINT32_MAX, blkid will
report no label, when a label does in fact exist. If such partitions are
listed in fstab by LABEL, they will mysteriously not mount.

This has been fixed upstream: http://git.kernel.org/?p=utils/util-linux
/util-linux.git;a=commit;h=7e256156f4a8650f0e5c5aaea9cf93d9bf3e1294 .
Upgrading to util-linux 2.19 or higher would fix this bug.
