Detail
| Multiple vulnerabilities has been discovered and corrected in libvirt: An out-of-bounds read flaw was found in the way libvirt's qemuDomainGetBlockIoTune() function looked up the disk index in a non-persistent (live) disk configuration while a persistent disk configuration was being indexed. A remote attacker able to establish a read-only connection to libvirtd could use this flaw to crash libvirtd or, potentially, leak memory from the libvirtd process (CVE-2014-3633). A denial of service flaw was found in the way libvirt's virConnectListAllDomains() function computed the number of used domains. A remote attacker able to establish a read-only connection to libvirtd could use this flaw to make any domain operations within libvirt unresponsive (CVE-2014-3657). The updated libvirt packages have been upgraded to the 1.1.3.6 version and patched to resolve these security flaws. |

| Title: | RHSA-2014:1352: libvirt security and bug fix update (Moderate) | ||
| 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 remote management of virtualized systems. An out-of-bounds read flaw was found in the way libvirt's qemuDomainGetBlockIoTune() function looked up the disk index in a non-persistent (live) disk configuration while a persistent disk configuration was being indexed. A remote attacker able to establish a read-only connection to libvirtd could use this flaw to crash libvirtd or, potentially, leak memory from the libvirtd process. (CVE-2014-3633) A denial of service flaw was found in the way libvirt's virConnectListAllDomains() function computed the number of used domains. A remote attacker able to establish a read-only connection to libvirtd could use this flaw to make any domain operations within libvirt unresponsive. (CVE-2014-3657) The CVE-2014-3633 issue was discovered by Luyao Huang of Red Hat. This update also fixes the following bug: * Prior to this update, libvirt was setting the cpuset.mems parameter for domains with numatune/memory[nodeset] prior to starting them. As a consequence, domains with such a nodeset, which excluded the NUMA node with DMA and DMA32 zones (found in /proc/zoneinfo), could not be started due to failed KVM initialization. With this update, libvirt sets the cpuset.mems parameter after the initialization, and domains with any nodeset (in /numatune/memory) can be started without an error. (BZ#1135871) All libvirt users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, libvirtd will be restarted automatically. | ||
