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:

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
