Advisory ID: RHSA-2012:0774-04
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-0774.html
Issue date: 2012-06-20
CVE Names: CVE-2012-2690
=====================================================================
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 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.
It was found that editing files with virt-edit left said files in a
world-readable state (and did not preserve the file owner or
Security-Enhanced Linux context). If an administrator on the host used
virt-edit to edit a file inside a guest, the file would be left with
world-readable permissions. This could lead to unprivileged guest users
accessing files they would otherwise be unable to. (CVE-2012-2690)
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 6.3 Technical
Notes for information on the most significant of these changes.
Users of libguestfs are advised to upgrade to these updated packages, which
fix 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
