The remote Red Hat host is missing one or more security updates.
Updated kernel packages that fix various security issues and several
bugs are now available for Red Hat Enterprise Linux 5.
This update has been rated as having important security impact by the
Red Hat Security Response Team.
The kernel packages contain the Linux kernel, the core of any Linux
These updated packages fix the following security issues :
* on AMD64 architectures, the possibility of a kernel crash was
discovered by testing the Linux kernel process-trace ability. This
could allow a local unprivileged user to cause a denial of service
(kernel crash). (CVE-2008-1615, Important)
* on 64-bit architectures, the possibility of a timer-expiration value
overflow was found in the Linux kernel high-resolution timers
functionality, hrtimer. This could allow a local unprivileged user to
setup a large interval value, forcing the timer expiry value to become
negative, causing a denial of service (kernel hang). (CVE-2007-6712,
* the possibility of a kernel crash was found in the Linux kernel
IPsec protocol implementation, due to improper handling of fragmented
ESP packets. When an attacker controlling an intermediate router
fragmented these packets into very small pieces, it would cause a
kernel crash on the receiving node during packet reassembly.
* a potential denial of service attack was discovered in the Linux
kernel PWC USB video driver. A local unprivileged user could use this
flaw to bring the kernel USB subsystem into the busy-waiting state,
causing a denial of service. (CVE-2007-5093, Low)
As well, these updated packages fix the following bugs :
* in certain situations, a kernel hang and a possible panic occurred
when disabling the cpufreq daemon. This may have prevented system
reboots from completing successfully.
* continual 'softlockup' messages, which occurred on the guest's
console after a successful save and restore of a Red Hat Enterprise
Linux 5 para-virtualized guest, have been resolved.
* in the previous kernel packages, the kernel may not have reclaimed
NFS locks after a system reboot.
Red Hat Enterprise Linux 5 users are advised to upgrade to these
updated packages, which contain backported patches to resolve these
