Joris van Rantwijk found a flaw in the Pygrub utility which is used as
a boot loader for guest domains. A malicious local administrator of a
guest domain could create a carefully crafted grub.conf file which
would trigger the execution of arbitrary code outside of that domain.
Tavis Ormandy discovered a heap overflow flaw during video-to-video
copy operations in the Cirrus VGA extension code used in Xen. A
malicious local administrator of a guest domain could potentially
trigger this flaw and execute arbitrary code outside of the domain.
Tavis Ormandy discovered insufficient input validation leading to a
heap overflow in the Xen NE2000 network driver. If the driver is in
use, a malicious local administrator of a guest domain could
potentially trigger this flaw and execute arbitrary code outside of
the domain. Xen does not use this driver by default. (CVE-2007-1321)
