Detail
| A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 13.10 - Ubuntu 12.10 - Ubuntu 12.04 LTS Summary: Several security issues were fixed in libvirt. Software Description: - libvirt: Libvirt virtualization toolkit Details: Martin Kletzander discovered that libvirt incorrectly handled reading memory tunables from LXC guests. A local user could possibly use this flaw to cause libvirtd to crash, resulting in a denial of service. This issue only affected Ubuntu 13.10. (CVE-2013-6436) Dario Faggioli discovered that libvirt incorrectly handled the libxl driver. A local user could possibly use this flaw to cause libvirtd to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 13.10. (CVE-2013-6457) It was discovered that libvirt contained multiple race conditions in block device handling. A remote read-only user could use this flaw to cause libvirtd to crash, resulting in a denial of service. (CVE-2013-6458) Eric Blake discovered that libvirt incorrectly handled certain ACLs. An attacker could use this flaw to possibly obtain certain sensitive information. This issue only affected Ubuntu 13.10. (CVE-2014-0028) Jiri Denemark discovered that libvirt incorrectly handled keepalives. A remote attacker could possibly use this flaw to cause libvirtd to crash, resulting in a denial of service. (CVE-2014-1447) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 13.10: Ubuntu 12.10: Ubuntu 12.04 LTS: After a standard system update you need to reboot your computer to make all the necessary changes.
