Synopsis

Low: libguestfs security, bug fix, and enhancement update

Type/Severity

Security Advisory Low

Topic

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.

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.

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