| Description: | 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 erroneous data provided by the Linux virtio-net driver, used by guest operating systems. Due to a deficiency in the TSO (TCP segment offloading) implementation, a guest's virtio-net driver would transmit improper data to a certain QEMU-KVM process on the host, causing the guest to crash. A remote attacker could use this flaw to send specially-crafted data to a target guest system, causing that guest to crash. (CVE-2010-0741)
Additionally, these updated packages include numerous bug fixes and enhancements. Refer to the KVM chapter of the Red Hat Enterprise Linux 5.5 Technical Notes for details:
http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.5/html/Technical_Notes/kvm.html
All KVM users should upgrade to these updated packages, which resolve this issue as well as fixing the bugs and adding the enhancements noted in the Technical Notes. Note: The procedure in the Solution section must be performed before this update will take effect.
