                   Red Hat Security Advisory

Synopsis:          Moderate: libguestfs security, bug fix, and enhancement update
Advisory ID:       RHSA-2013:1536-02
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2013-1536.html
Issue date:        2013-11-21
CVE Names:         CVE-2013-4419 
=====================================================================

1. Summary:

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

The Red Hat Security Response Team has rated this update as having moderate
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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 6) - x86_64
Red Hat Enterprise Linux Desktop Optional (v. 6) - x86_64

3. Description:

Libguestfs is a library and set of tools for accessing and modifying guest
disk images.

It was found that guestfish, which enables shell scripting and command line
access to libguestfs, insecurely created the temporary directory used to
store the network socket when started in server mode. A local attacker
could use this flaw to intercept and modify other user's guestfish command,
allowing them to perform arbitrary guestfish actions with the privileges of
a different user, or use this flaw to obtain authentication credentials.
(CVE-2013-4419)

This issue was discovered by Michael Scherer of the Red Hat Regional IT
team.

These updated libguestfs packages include numerous bug fixes and
enhancements. Space precludes documenting all of these changes in this
advisory. Users are directed to the Red Hat Enterprise Linux 6.5 Technical
Notes, linked to in the References, for information on the most significant
of these changes.

All libguestfs users are advised to upgrade to these updated packages,
which contain backported patches to correct these issues and add these
enhancements.

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/site/articles/11258
