Arbitrary Code Execution

xen is vulnerable to privilege escalation. The vulnerability exists as it was found to allow unprivileged DomU domains to overwrite xenstore values which should only be changeable by the privileged Dom0 domain. An attacker controlling a DomU domain could, potentially, use this flaw to kill...

Arbitrary File Overwrite

xen is vulnerable to arbitrary file overwrite. The vulnerability exists as it was discovered that the qemu-dm.debug script created a temporary file in /tmp in an insecure way. A local attacker in Dom0 could, potentially, use this flaw to overwrite arbitrary files via a symlink attack...

Denial Of Service (DoS)

xen is vulnerable to denial of service DoS. The vulnerability exists as it was discovered that the hypervisor's para-virtualized framebuffer PVFB backend failed to validate the frontend's framebuffer description properly. This could allow a privileged user in the unprivileged domain DomU to cause...
