tavis ormandy discovered a heap overflow flaw during video-to-video
copy operations in the cirrus vga extension code that is used in xen.
a malicious local administrator of a guest domain could potentially
trigger this flaw and execute arbitrary code outside of the domain
(cve-2007-1320).

problem description:
tavis ormandy discovered a heap overflow flaw during video-to-video
copy operations in the cirrus vga extension code that is used in xen.
a malicious local administrator of a guest domain could potentially
trigger this flaw and execute arbitrary code outside of the domain
(cve-2007-1320).
tavis ormandy also discovered insufficient input validation leading to
a heap overflow in the ne2000 network driver in xen. 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 (cve-2007-1321, cve-2007-5729, cve-2007-5730).
steve kemp found that xen-utils used insecure temporary files within
the xenmon tool that could allow local users to truncate arbitrary
files (cve-2007-3919).
joris van rantwijk discovered a flaw in pygrub, 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
could trigger the execution of arbitrary code outside of that domain
(cve-2007-4993).
updated packages have been patched to prevent these issues.
