xend in Xen 3.3.0 does not properly restrict a guest VM's write access within the /local/domain xenstore directory tree, which allows guest OS users to cause a denial of service and possibly have unspecified other impact by writing to (1) console/tty, (2) console/limit, or (3) image/device-model-pid. NOTE: this issue exists because of erroneous set_permissions calls in the fix for CVE-2008-4405.

Security readout for executives and security teams

CVE-2008-5716 is a Xen 3.3.0 xend permission flaw. A guest VM could write to parts of xenstore that should have been protected, creating denial-of-service risk and possible unspecified additional impact. The record links this to an incomplete prior fix for CVE-2008-4405. Exposure is most likely in legacy Xen 3.3.0 environments or downstream packages carrying the incomplete CVE-2008-4405 fix. Modern maintained Xen deployments may not be affected, but the provided sources do not enumerate fixed versions. Treat this as a legacy virtualization hygiene issue. Prioritize if the business still runs Xen 3.3.0 or old vendor builds; otherwise document non-exposure and close with evidence. Mitigation focus: Inventory Xen hosts and identify any Xen 3.3.0 or legacy xend deployments.; Check vendor or distribution advisories for the corrected xenstore permission fix.; Apply maintained Xen packages or a vendor-supported backport addressing CVE-2008-5716..
