3. Description:

The util-linux-ng packages contain a large variety of low-level system
utilities that are necessary for a Linux operating system to function.

An information disclosure flaw was found in the way the mount command
reported errors. A local attacker could use this flaw to determine the
existence of files and directories they do not have access to.
(CVE-2013-0157)

These updated util-linux-ng packages include numerous bug fixes and
enhancements. Space precludes documenting all of these changes in this

of these changes.

All users of util-linux-ng are advised to upgrade to these updated
packages, which contain backported patches to correct these issues and add
these enhancements.
