Zusammenfassung:	NOSUMMARY
Beschreibung:	Description: The remote host is missing updates announced in advisory RHSA-2010:0615. The libvirt library is a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. In addition, libvirt provides tools for remotely managing virtualized systems. It was found that libvirt did not set the user-defined backing store format when creating a new image, possibly resulting in applications having to probe the backing store to discover the format. A privileged guest user could use this flaw to read arbitrary files on the host. (CVE-2010-2239) It was found that libvirt created insecure iptables rules on the host when a guest system was configured for IP masquerading, allowing the guest to use privileged ports on the host when accessing network resources. A privileged guest user could use this flaw to access network resources that would otherwise not be accessible to the guest. (CVE-2010-2242) Red Hat would like to thank Jeremy Nickurak for reporting the CVE-2010-2242 issue. All users of libvirt are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the system must be rebooted for the update to take effect. Solution: Please note that this update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date http://rhn.redhat.com/errata/RHSA-2010-0615.html http://www.redhat.com/security/updates/classification/#low Risk factor : Medium CVSS Score: 4.4
