User Rating:      How can I rate this item?
Posted by Benjamin D. Thomas   
RedHat Linux Updated util-linux packages that fix a security issue are now available for Red Hat Enterprise Linux 3, 4, and 5. A flaw was discovered in the way that the mount and umount utilities used the setuid and setgid functions, which could lead to privileges being dropped improperly. A local user could use this flaw to run mount helper applications such as, mount.nfs, with additional privileges. This update has been rated as having moderate security impact by the Red Hat Security Response Team.

3. Problem description:

The util-linux package contains a large variety of low-level system
utilities that are necessary for a Linux system to function. 

A flaw was discovered in the way that the mount and umount utilities
used the setuid and setgid functions, which could lead to privileges being
dropped improperly.  A local user could use this flaw to run mount helper
applications such as, mount.nfs, with additional privileges (CVE-2007-5191).

Users are advised to update to these erratum packages which contain a
backported patch to correct this issue.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
