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.

All libguestfs users are advised to upgrade to these updated packages, which correct this issue, and fix the bugs and add the enhancement.
