CentOS Errata and Security Advisory CESA-2010:0898
KVM (Kernel-based Virtual Machine) is a full virtualization solution for
Linux on AMD64 and Intel 64 systems. KVM is a Linux kernel module built for
the standard Red Hat Enterprise Linux kernel.
A flaw was found in the way QEMU-KVM handled the reloading of fs and gs
segment registers when they had invalid selectors. A privileged host user
with access to “/dev/kvm” could use this flaw to crash the host (denial of
service). (CVE-2010-3698)
All KVM users should upgrade to these updated packages, which contain a
backported patch to correct this issue. Note: The procedure in the Solution
section must be performed before this update will take effect.
