The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2011:1691 advisory.

  - util-linux: mount fails to anticipate RLIMIT_FSIZE (CVE-2011-1675)

  - util-linux: umount may fail to remove /etc/mtab~ lock file (CVE-2011-1677)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Multiple vulnerabilities has been discovered and corrected in util-linux :

mount in util-linux 2.19 and earlier attempts to append to the /etc/mtab.tmp file without first checking whether resource limits would interfere, which allows local users to trigger corruption of the /etc/mtab file via a process with a small RLIMIT_FSIZE value, a related issue to CVE-2011-1089 (CVE-2011-1675).

mount in util-linux 2.19 and earlier does not remove the /etc/mtab~ lock file after a failed attempt to add a mount entry, which has unspecified impact and local attack vectors (CVE-2011-1677).

The updated packages have been patched to correct this issue.

The remote Redhat Enterprise Linux 4 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - util-linux: umount may fail to remove /etc/mtab~ lock file (CVE-2011-1677)

  - mount in util-linux 2.19 and earlier attempts to append to the /etc/mtab.tmp file without first checking     whether resource limits would interfere, which allows local users to trigger corruption of the /etc/mtab     file via a process with a small RLIMIT_FSIZE value, a related issue to CVE-2011-1089. (CVE-2011-1675)

  - (a) mount and (b) umount in util-linux 2.14.1, 2.17.2, and probably other versions allow local users to     determine the existence of restricted directories by (1) using the --guess-fstype command-line option or     (2) attempting to mount a non-existent device, which generates different error messages depending on     whether the directory exists. (CVE-2013-0157)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

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

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 :

  - Due to a hard-coded limit of 128 devices, an attempt to     run the 'blkid -c' command on more than 128 devices     caused blkid to terminate unexpectedly. This update     increases the maximum number of devices to 8192 so that     blkid no longer crashes in this scenario.

  - Previously, the 'swapon -a' command did not detect     device-mapper devices that were already in use. This     update corrects the swapon utility to detect such     devices as expected.

  - Prior to this update, the presence of an invalid line in     the /etc/fstab file could cause the umount utility to     terminate unexpectedly with a segmentation fault. This     update applies a patch that corrects this error so that     umount now correctly reports invalid lines and no longer     crashes.

  - Previously, an attempt to use the wipefs utility on a     partitioned device caused the utility to terminate     unexpectedly with an error. This update adapts wipefs to     only display a warning message in this situation.

  - When providing information on interprocess communication     (IPC) facilities, the ipcs utility could previously     display a process owner as a negative number if the     user's UID was too large. This update adapts the     underlying source code to make sure the UID values are     now displayed correctly.

  - In the installation scriptlets, the uuidd package uses     the chkconfig utility to enable and disable the uuidd     service. Previously, this package did not depend on the     chkconfig package, which could lead to errors during     installation if chkconfig was not installed. This update     adds chkconfig to the list of dependencies so that such     errors no longer occur.

  - The previous version of the     /etc/udev/rules.d/60-raw.rules file contained a     statement that both this file and raw devices are     deprecated. This is no longer true and the Scientific     Linux kernel supports this functionality. With this     update, the aforementioned file no longer contains this     incorrect statement.

  - Previously, an attempt to use the cfdisk utility to read     the default Scientific Linux 6 partition layout failed     with an error. This update corrects this error and the     cfdisk utility can now read the default partition layout     as expected.

  - The previous version of the tailf(1) manual page     incorrectly stated that users can use the     '--lines=NUMBER' command line option to limit the number     of displayed lines. However, the tailf utility does not     allow the use of the equals sign (=) between the option     and its argument. This update corrects this error.

  - The fstab(5) manual page has been updated to clarify     that empty lines in the /etc/fstab configuration file     are ignored.

As well, this update adds the following enhancements :

  - A new fstrim utility has been added to the package. This     utility allows the root user to discard unused blocks on     a mounted file system.

  - The login utility has been updated to provide support     for failed login attempts that are reported by PAM.

  - The lsblk utility has been updated to provide additional     information about the topology and status of block     devices.

  - The agetty utility has been updated to pass the hostname     to the login utility.

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.

The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2011-1691 advisory.

  - mount in util-linux 2.19 and earlier attempts to append to the /etc/mtab.tmp file without first checking     whether resource limits would interfere, which allows local users to trigger corruption of the /etc/mtab     file via a process with a small RLIMIT_FSIZE value, a related issue to CVE-2011-1089. (CVE-2011-1675)

  - mount in util-linux 2.19 and earlier does not remove the /etc/mtab~ lock file after a failed attempt to     add a mount entry, which has unspecified impact and local attack vectors. (CVE-2011-1677)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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.

(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.

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

  - 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.

  - 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.

  - 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.

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.

  - This update adds the 'fsfreeze' command which halts     access to a file system on a disk.

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.
