Description:
A weakness has been reported in Xen, which can be exploited by malicious, local users in a Xen DomU to bypass certain security restrictions.
The weakness is caused due to certain XenStore variables (e.g. /local/domain/<domid>/console/tty and /local/domain/<domid>/console/vnc-port) being writable from within the corresponding Xen DomU domain. This can be exploited to overwrite the variables, which may be processed with potentially unsafe values in applications running in Dom0.
