Red Hat Bugzilla – Bug 971503
CVE-2013-2211 xen: libxl allows guest write access to sensitive console related xenstore keys
Last modified: 2013-06-26 03:29:33 EDT
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.
Red Hat would like to thank the Xen project for reporting this issue.
This issue does not affect the versions of the xen package as shipped with Red Hat Enterprise Linux 5 as it does not provide support for the libxl toolstack.
This issue does not affect Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG.
