Detail
Problem Description: Updated libvirt packages that fix one security issue and one bug 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: Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 3. Description: 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. A flaw was found in the way libvirtd handled error reporting for concurrent connections. A remote attacker able to establish read-only connections to libvirtd on a server could use this flaw to crash libvirtd. (CVE-2011-1486) This update also fixes the following bug: * Previously, running qemu under a different UID prevented it from accessing files with mode 0660 permissions that were owned by a different user, but by a group that qemu was a member of. (BZ#668692) All libvirt users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues. After installing the updated packages, libvirtd must be restarted ("service libvirtd restart") for this update to take effect. 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 https://access.redhat.com/kb/docs/DOC-11259 5. Bugs fixed (http://bugzilla.redhat.com/): 668692 - qemu process is spawned with no supplementary groups 693391 - CVE-2011-1486 libvirt: error reporting in libvirtd is not thread safe |

Title: | DSA-2280-1 libvirt -- several | ||
Description: | It was discovered that libvirt, a library for interfacing with different virtualization systems, is prone to an integer overflow. Additionally, the stable version is prone to a denial of service, because its error reporting is not thread-safe. For the stable distribution, these problems have been fixed in version 0.8.3-5+squeeze2. | ||
