Fedora 7 : xen-3.1.0-6.fc7 (2007-2270)

Synopsis :

The remote Fedora host is missing a security update.

Description :

Fixes a security flaw in pygrub handling of config files and a
denial-of-service case in ne2k NIC for QEMU.

Fixes the case of disappearing network cards in fully-virtualized
guests. NB, it only fixes it for guests created after this errata is
installed & XenD restarted. Any pre-existing guests may continue to
have problems. To fix existing guests, first ensure XenD has been
restarted (service xend restart), then use virt-manager/virsh to
remove the network card, and then add it back. This will correct the
configuration stored in XenD permanently.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
