Description Petr Matousek 2011-05-02 09:09:27 UTC
A flaw was found in the way Xen hypervisor checked for upper boundary when
getting a new event channel port. A privileged DomU user could use this
flaws to cause denial of service or, possibly, increase his privileges.

Comment 16 Petr Matousek 2011-05-03 11:56:07 UTC

This issue only affects Red Hat Enterprise Linux 5 as we did not backport upstream Xen unstable commit 2dcdd2fcb945. The versions of the Linux kernel as shipped with Red Hat Enterprise Linux 4, 6, and Red Hat Enterprise MRG are not affected.
