Base vector

AV:L/AC:L/Au:N/C:C/I:C/A:C

Name of the Vulnerable Software and Affected Versions Xen version 3.3.0

Description The issue allows guest OS users to cause a denial of service and possibly have unspecified other impact by writing to certain files. This can be done by writing to (1) console/tty, (2) console/limit, or (3) image/device-model-pid within the /local/domain xenstore directory tree.

Recommendations For Xen version 3.3.0, consider restricting write access to the /local/domain xenstore directory tree to prevent guest OS users from causing a denial of service. As a temporary workaround, restrict access to the console/tty, console/limit, and image/device-model-pid files to minimize the risk of exploitation.
