Description Jan Lieskovsky 2007-11-12 05:53:47 EST
Description of problem:

Xen 3.1.1 allows virtual guest system users to cause a denial of
service (hypervisor crash) by using a debug register (DR7) to set
certain breakpoints. (CVE-2007-5906).
Comment 1 Rik van Riel 2007-11-12 12:19:44 EST
Will this bugzilla get the details needed to fix the bug, once those details
become available?
Comment 3 Jan Lieskovsky 2007-11-16 09:57:18 EST
The official post is here -- there is also patch provided: 
Comment 5 Mark J. Cox 2008-06-25 07:02:25 EDT
Note that the rebase of the Xen hypervisor to 3.1.2 in the 5.2 kernel
(RHBA-2008:0314) caused this issue to be fixed for Enterprise Linux 5.  I'll
therefore update that advisory so that it references this CVE name.
Comment 6 Chris Lalancette 2009-09-10 12:30:52 EDT
This was fixed long ago in all of the relevant released, so I'll close out this tracker bug.
