Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated xen packages that fix one security issue are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The xen packages contain administration tools and the xend service for managing the kernel-xen kernel for virtualization on Red Hat Enterprise Linux.

A flaw was found in the way QEMU emulated the e1000 network interface card when the host was configured to accept jumbo network frames, and a fully-virtualized guest using the e1000 emulated driver was not. A remote attacker could use this flaw to crash the guest or, potentially, execute arbitrary code with root privileges in the guest.
(CVE-2012-6075)

All users of xen are advised to upgrade to these updated packages, which correct this issue. After installing the updated packages, all running fully-virtualized guests must be restarted for this update to take effect.

Solution

Update the affected packages.
