The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2010:0271 advisory.

    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.
