The remote host is missing updates announced in
advisory RHSA-2010:0041.
The kernel-rt packages contain the Linux kernel, the core of any Linux
operating system.
This update fixes the following security issues:
* an array index error was found in the gdth driver in the Linux kernel. A
local user could send a specially-crafted IOCTL request that would cause a
denial of service or, possibly, privilege escalation. (CVE-2009-3080,
Important)
* a flaw was found in the FUSE implementation in the Linux kernel. When a
system is low on memory, fuse_put_request() could dereference an invalid
pointer, possibly leading to a local denial of service or privilege
escalation. (CVE-2009-4021, Important)
* a flaw was found in each of the following Intel PRO/1000 Linux drivers in
the Linux kernel: e1000 and e1000e. A remote attacker using packets larger
than the MTU could bypass the existing fragment check, resulting in
partial, invalid frames being passed to the network stack. These flaws
could also possibly be used to trigger a remote denial of service.
(CVE-2009-4536, CVE-2009-4538, Important)
* a flaw was found in the Realtek r8169 Ethernet driver in the Linux
kernel. Receiving overly-long frames with a certain revision of the network
cards supported by this driver could possibly result in a remote denial of
service. (CVE-2009-4537, Important)
These updated packages also include other bug fixes. Users are directed to
the Red Hat Enterprise MRG 1.2 Release Notes for information on those
fixes, available shortly from:
http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_MRG/
Users should upgrade to these updated packages, which contain backported
patches to correct these issues. The system must be rebooted for this
update to take effect.
Solution:
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
