CVE-2008-4405 Information

Description

xend in Xen 3.0.3 does not properly limit the contents of the /local/domain xenstore directory tree and does not properly restrict a guest VM’s write access within this 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 was originally reported as an issue in libvirt 0.3.3 and xenstore but CVE is considering the core issue to be related to Xen.
