CVE-2008-5716

Xen 3.3.0 - Denial of Service via Xenstore Directory Write Access

Title source: llm

Description

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.
