CVE-2013-2211 xen: libxl allows guest write access to sensitive console related xenstore keys
The libxenlight (libxl) toolstack library does not correctly set permissions on xenstore keys relating to paravirtualised and emulated serial console devices. This could allow a malicious guest administrator to change values in xenstore which the host later relies on being implicitly trusted.
