Denial of Service Vulnerability in Xen Hypervisor
CVE-2008-4405
What is CVE-2008-4405?
The Xen hypervisor version 3.0.3 has a vulnerability where the xend component fails to adequately restrict the contents of the /local/domain xenstore directory tree. This improper configuration allows a guest virtual machine (VM) to write to sensitive areas such as console/tty, console/limit, and image/device-model-pid. As a result, malicious users within the guest OS may exploit this flaw to create a denial of service situation, potentially affecting the availability of the host or other VMs. The issue is notable for its implications on VM security and resource management within virtualized environments.
