CVE-2007-4993

By use of a specially crafted grub configuration file a domU user may be able to execute arbitrary code upon the dom0 when pygrub is being used.

CVE-2007-1320

Multiple heap-based buffer overflows in the Cirrus VGA extension, provided by QEMU, may allow local users to execute arbitrary code via bitblt heap overflow.

For the stable distribution (etch), these problems have been fixed in version 3.0.3-0-3.

For the unstable distribution (sid), these problems will be fixed soon.

We recommend that you upgrade your xen-utils package.");
