Scientific Linux Security Update : xen/libvirt on SL5.0 i386/x86_64

high Nessus Plugin ID 60325

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

NOTE1: The xen update needs to be applied with the new kernel kernel-2.6.18-53.1.4.el5. Because a kernel does not automatically get updated, but the xen libraries do (by default) it is best to upgrade them both at the same time, and then reboot into the new kernel.

Updating both the kernel and xen is because the new kernel has changed the way that it works with xen. So upgrading and booting into the new kernel will break your old xen. And updating xen and trying to restart xen domains in your old kernel will not work either.

Updating the xen libraries will not affect currently running virtual machines, but will prevent any new ones being started or rebooted, until you have booted into the new kernel.

NOTE2: This xen/kernel update is only really needed for the master virtual machine (Dom 0). Virtual machines can update their kernels without any problems.

Solution

Update the affected packages.
