The remote Redhat Enterprise Linux 5 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2012:0307 advisory.

    The util-linux package contains a large variety of low-level system     utilities that are necessary for a Linux system to function. Among others,     util-linux contains the fdisk configuration tool and the login program.

    Multiple flaws were found in the way the mount and umount commands     performed mtab (mounted file systems table) file updates. A local,     unprivileged user allowed to mount or unmount file systems could use these     flaws to corrupt the mtab file and create a stale lock file, preventing     other users from mounting and unmounting file systems. (CVE-2011-1675,     CVE-2011-1677)

    This update also fixes the following bugs:

    * When the user logged into a telnet server, the login utility did not     update the utmp database properly if the utility was executed from the     telnetd daemon. This was due to telnetd not creating an appropriate entry     in a utmp file before executing login. With this update, correct entries     are created and the database is updated properly. (BZ#646300)

    * Various options were not described on the blockdev(8) manual page. With     this update, the blockdev(8) manual page includes all the relevant options.
    (BZ#650937)

    * Prior to this update, the build process of the util-linux package failed     in the po directory with the following error message: @MKINSTALLDIRS@:
    No such file or directory. An upstream patch has been applied to address     this issue, and the util-linux package now builds successfully. (BZ#677452)

    * Previously, the ipcs(1) and ipcrm(1) manual pages mentioned an invalid     option, -b. With this update, only valid options are listed on those     manual pages. (BZ#678407)

    * Previously, the mount(8) manual page contained incomplete information     about the ext4 and XFS file systems. With this update, the mount(8) manual     page contains the missing information. (BZ#699639)

    In addition, this update adds the following enhancements:

    * Previously, if DOS mode was enabled on a device, the fdisk utility could     report error messages similar to the following:

    Partition 1 has different physical/logical beginnings (non-Linux?):
    phys=(0, 1, 1) logical=(0, 2, 7)

    This update enables users to switch off DOS compatible mode (by specifying     the -c option), and such error messages are no longer displayed.
    (BZ#678430)

    * This update adds the fsfreeze command which halts access to a file     system on a disk. (BZ#726572)

    All users of util-linux are advised to upgrade to this updated package,     which contains backported patches to correct these issues and add these     enhancements.
