====================================================================
1. Summary:

Updated libguestfs packages that fix one security issue, several bugs, and
add one enhancement are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having low
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.

3. Description:

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.

4. Solution:

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

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/kb/docs/DOC-11259
