Fedora 7 : xen-3.1.0-6.fc7 (2007-2270)
Medium Nessus Plugin ID 27763
SynopsisThe remote Fedora host is missing a security update.
DescriptionFixes 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.
SolutionUpdate the affected packages.
