CentOS Update for kernel CESA-2013:0911 centos6

The remote host is missing an update for the 'kernel' package(s) announced via the referenced advisory.

The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues: * A flaw was found in the way KVM (Kernel-based Virtual Machine) initialized a guest's registered pv_eoi (paravirtualized end-of-interrupt) indication flag when entering the guest. An unprivileged guest user could potentially use this flaw to crash the host. (CVE-2013-1935, Important) * A missing sanity check was found in the kvm_set_memory_region() function in KVM, allowing a user-space process to register memory regions pointing to the kernel address space. A local, unprivileged user could use this flaw to escalate their privileges. (CVE-2013-1943, Important) * A double free flaw was found in the Linux kernel's Virtual Ethernet Tunnel driver (veth). A remote attacker could possibly use this flaw to crash a target system. (CVE-2013-2017, Moderate) Red Hat would like to thank IBM for reporting the CVE-2013-1935 issue and Atzm WATANABE of Stratosphere Inc. for reporting the CVE-2013-2017 issue. The CVE-2013-1943 issue was discovered by Michael S. Tsirkin of Red Hat. This update also fixes several bugs and adds one enhancement. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section. Users should upgrade to these updated packages, which contain backported patches to correct these issues and add this enhancement. The system must be rebooted for this update to take effect.
