|Bugzilla:||500945: CVE-2009-1758 kernel: xen: local denial of service|
The MITRE CVE dictionary describes this issue as:
The hypervisor_callback function in Xen, possibly before 3.4.0, as applied to the Linux kernel 2.6.30-rc4, 2.6.18, and probably other versions allows guest user applications to cause a denial of service (kernel oops) of the guest OS by triggering a segmentation fault in "certain address ranges."
This issue did not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 2.1, 3, and Red Hat Enterprise MRG. It was addressed in Red Hat Enterprise Linux 4 and 5 via https://rhn.redhat.com/errata/RHSA-2009-1132.html and https://rhn.redhat.com/errata/RHSA-2009-1106.html .
