tag_insight = "The kernel packages contain the Linux kernel, the core of any Linux
operating system.
This update fixes the following security issues:
* A flaw was found in the way the Xen hypervisor implementation handled
instruction emulation during virtual machine exits. A malicious user-space
process running in an SMP guest could trick the emulator into reading a
different instruction than the one that caused the virtual machine to exit.
An unprivileged guest user could trigger this flaw to crash the host. This
only affects systems with both an AMD x86 processor and the AMD
Virtualization (AMD-V) extensions enabled. (CVE-2011-1780, Important)
* A flaw allowed the tc_fill_qdisc() function in the Linux kernel's packet
scheduler API implementation to be called on built-in qdisc structures. A
local, unprivileged user could use this flaw to trigger a NULL pointer
dereference, resulting in a denial of service. (CVE-2011-2525, Moderate)
* A flaw was found in the way space was allocated in the Linux kernel's
Global File System 2 (GFS2) implementation. If the file system was almost
full, and a local, unprivileged user made an fallocate() request, it could
result in a denial of service. Note: Setting quotas to prevent users from
using all available disk space would prevent exploitation of this flaw.
(CVE-2011-2689, Moderate)
These updated kernel packages include a number of bug fixes and
enhancements. Space precludes documenting all of these changes in this
advisory. Refer to the Red Hat Enterprise Linux 5.7 Technical Notes for
information about the most significant bug fixes and enhancements included
in this update:
https://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/html/5.7_Technical_Notes/kernel.html#RHSA-2011-1065
All Red Hat Enterprise Linux 5 users are advised to install these updated
packages, which correct these issues. The system must be rebooted for this
update to take effect.";
