The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2011:0586 advisory.

    libguestfs is a library for accessing and modifying guest disk images.

    libguestfs relied on the format auto-detection in QEMU rather than     allowing the guest image file format to be specified. A privileged guest     user could potentially use this flaw to read arbitrary files on the host     that were accessible to a user on that host who was running a program that     utilized the libguestfs library. (CVE-2010-3851)

    This erratum upgrades libguestfs to upstream version 1.7.17, which includes     a number of bug fixes and one enhancement. Documentation for these bug     fixes and this enhancement is provided in the Technical Notes document,     linked to in the References section.

    All libguestfs users are advised to upgrade to these updated packages,     which correct this issue, and fix the bugs and add the enhancement noted     in the Technical Notes.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

    [1.7.17-17]
    - Remove dependency on gfs2-utils.
      resolves: rhbz#695138

    [1.7.17-16]
    - Canonicalize /dev/vd* paths in virt-inspector code.
      resolves: rhbz#691724

    [1.7.17-15]
    - Fix trace segfault for non-daemon functions.
      resolves: rhbz#676788

    [1.7.17-14]
    - Add explicit BuildRequires for latest augeas. (RHBZ#677616)

    [1.7.17-13]
    - Rebuild to pick up new augeas lens (RHBZ#677616)

    [1.7.17-12]
    - Fix typo in virt-make-fs manual page.
      resolves: rhbz#673721
    - Add a grep-friendly string to LIBGUESTFS_TRACE output.
      resolves: rhbz#673477

    [1.7.17-11]
    - Only runtime require febootstrap-supermin-helper (not whole of       febootstrap) (RHBZ#669840).

    [1.7.17-10]
    - Remove external hexedit script and make guestfish users set .
      This is because requiring emacs pulls in all of X (RHBZ#641494).

    [1.7.17-9]
    - Fix: guestfish fails when guest fstab entry does not exist (RHBZ#668611).

    [1.7.17-8]
    - Backport patches up to upstream 1.8.1. (RHBZ#613593)
    - Fixes:
       * guestfish: fails to tilde expand '~' when /home/ksharma unset (RHBZ#617440)
       * libguestfs: unknown filesystem /dev/fd0 (RHBZ#666577)
       * libguestfs: unknown filesystem label SWAP-sda2 (RHBZ#666578)
       * libguestfs: unknown filesystem /dev/hd{x} (cdrom) (RHBZ#666579)
       * virt-filesystems fails on guest with corrupt filesystem label (RHBZ#668115)
       * emphasize 'libguestfs-winsupport' in error output (RHBZ#627468)

    [1.7.17-4]
    - Backport patches up to upstream 1.8.0 _except_ for:
       * changes which require febootstrap 3.x
       * changes which were only relevant for other distros

    [1.7.17-3]
    - New upstream version 1.7.17, rebase for RHEL 6.1 (RHBZ#613593).
    - Require febootstrap >= 2.11.
    - Split out new libguestfs-tools-c package from libguestfs-tools.
      . This is so that the -tools-c package can be pulled in by people         wanting to avoid a dependency on Perl, while -tools pulls in everything         as before.
      . The C tools currently are: cat, df, filesystems, fish, inspector, ls,         mount, rescue.
      . libguestfs-tools no longer pulls in guestfish.
    - guestfish no longer requires pod2text, hence no longer requires perl.
    - guestfish also depends on: less, man, vi, emacs.
    - Add BR db4-utils (although since RPM needs it, it not really necessary).
    - Runtime requires on db4-utils should be on core lib, not tools package.
    - Change all 'Requires: perl-Foo' to 'Requires: perl(Foo)'.
    - New manual pages containing example code.
    - Ship examples for C, OCaml, Ruby, Python.
    - Don't ship HTML versions of man pages.
    - Rebase no-fuse-test patch to latest version.
    - New tool: virt-filesystems.
    - Rename perl-libguestfs as perl-Sys-Guestfs (RHBZ#652587).
    - Remove guestfs-actions.h and guestfs-structs.h.  Libguestfs now     [header file.]
    - Add AUTHORS file from tarball.

    [1.6.2-4]
    - New upstream stable version 1.6.2, rebase for RHEL 6.1 (RHBZ#613593).
    - Remove previous patches which are now all upstream and in this new version.
    - BR febootstrap 2.10 (RHBZ#628849).
    - BR cryptsetup-luks for new LUKS encryption support.
    - ocaml-xml-light{,-devel} is no longer required to build.
    - guestfish is no longer dependent on virt-inspector.
    - Require the ruby package.
    - Disable PHP and Haskell bindings in configure (they wouldn't build anyway,       but this will help people building from source).
    - Set sysconfdir in configure.
    - --enable-debug-command is no longer required by configure script.
    - New command 'virt-make-fs'.
    - Include virt-inspector2, upstream replacement for virt-inspector.
    - Provide hexedit replacement script for guestfish.
    - BR autotools, and rerun after applying patches.

The remote MiracleLinux 4 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2011-500:01 advisory.

    Libguestfs is a library for accessing and modifying guest disk images.
    Amongst the things this is good for: making batch configuration changes to guests, getting disk used/free     statistics (see also: virt-df), migrating between virtualization systems (see also: virt-p2v), performing     partial backups, performing partial guest clones, cloning guests and changing registry/UUID/hostname info,     and much else besides.
    Libguestfs uses Linux kernel and qemu code, and can access any type of guest filesystem that Linux and     qemu can, including but not limited to: ext2/3/4, btrfs, FAT and NTFS, LVM, many different disk partition     schemes, qcow, qcow2, vmdk.
    Libguestfs provides ways to enumerate guest storage (eg. partitions, LVs, what filesystem is in each LV,     etc.).  It can also run commands in the context of the guest.
    Libguestfs is a library that can be linked with C and C++ management programs.
    See also the 'guestfish' package for shell scripting and command line access, and 'libguestfs-mount' for     mounting guest filesystems on the host using FUSE.
    For Perl bindings, see 'perl-Sys-Guestfs'.
    For OCaml bindings, see 'ocaml-libguestfs-devel'.
    For Python bindings, see 'python-libguestfs'.
    For Ruby bindings, see 'ruby-libguestfs'.
    For Java bindings, see 'libguestfs-java-devel'.
    Security issues fixed with this release     CVE-2010-3851     libguestfs before 1.5.23, as used in virt-v2v, virt-inspector 1.5.3 and earlier, and possibly other     products, when a raw-format disk image is used, allows local guest OS administrators to read files from     the host via a crafted (1) qcow2, (2) VMDK, or (3) VDI header, related to lack of support for a disk     format specifier.
    This update also upgrades libguestfs to upstream version 1.7.17, which includes a number of bug fixes and     enhancements, too many to list here. Please refer to the changelog.
