https://notcve.org/view.php?id=CVE-2010-3699
08 Dec 2010 — The backend driver in Xen 3.x allows guest OS users to cause a denial of service via a kernel thread leak, which prevents the device and guest OS from being shut down or create a zombie domain, causes a hang in zenwatch, or prevents unspecified xm commands from working properly, related to (1) netback, (2) blkback, or (3) blktap. El driver backend en Xen v3.x permite a usuarios del OS causar una denegación de servicio a través de una fuga en el hilo del kernel, lo que evita que el dispositivo y el invitado ... • http://lists.opensuse.org/opensuse-security-announce/2011-01/msg00007.html • CWE-399: Resource Management Errors •

05 Oct 2009 — The pyGrub boot loader in Xen 3.0.3, 3.3.0, and Xen-3.3.1 does not support the password option in grub.conf for para-virtualized guests, which allows attackers with access to the para-virtualized guest console to boot the guest or modify the guest's kernel boot parameters without providing the expected password. El pyGrub en Xen v3.0.3, v3.3.0, y Xen-3.3.1 no soporta la opción password en grub.conf para las invitaciones "para-virtualized", lo que permite a atacantes con acceso a la consola invitada para-vir... • https://www.exploit-db.com/exploits/33255 • CWE-264: Permissions, Privileges, and Access Controls •

22 May 2009 — The hypervisor_callback function in Xen, possibly before 3.4.0, as applied to the Linux kernel 2.6.30-rc4, 2.6.18, and probably other versions allows guest user applications to cause a denial of service (kernel oops) of the guest OS by triggering a segmentation fault in "certain address ranges."

24 Dec 2008 — 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. xend en Xen 3.3.0 no restringe adecuadamente el acceso de escritura de una máquina virtual invitada en el árbol d... • http://lists.xensource.com/archives/html/xen-devel/2008-12/msg00842.html • CWE-264: Permissions, Privileges, and Access Controls •
