Name        : kernel
Product     : Fedora 8
Version     : 2.6.26.6
Release     : 49.fc8
URL         : http://www.kernel.org/
Summary     : The Linux kernel
Description :
The kernel package contains the Linux kernel (vmlinuz), the core of any
Linux operating system.  The kernel handles the basic functions
of the operating system: memory allocation, process allocation, device
input and output, etc.

--------------------------------------------------------------------------------
Update Information:

Update kernel from version 2.6.26.5 to 2.6.26.6:
http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.26.6    CVE-2008-3831
An IOCTL in the i915 driver was not properly restricted to users with the
proper capabilities to use it.    CVE-2008-4410  The vmi_write_ldt_entry
function in arch/x86/kernel/vmi_32.c in the Virtual  Machine Interface (VMI) in
the Linux kernel 2.6.26.5 invokes write_idt_entry  where write_ldt_entry was
intended, which allows local users to cause a  denial of service (persistent
application failure) via crafted function calls,  related to the Java Runtime
Environment (JRE) experiencing improper LDT  selector state, a different
vulnerability than CVE-2008-3247.    CVE-2008-3525  The sbni_ioctl function in
drivers/net/wan/sbni.c in the wan subsystem in  the Linux kernel 2.6.26.3 does
not check for the CAP_NET_ADMIN capability  before processing a (1)
SIOCDEVRESINSTATS, (2) SIOCDEVSHWSTATE, (3)  SIOCDEVENSLAVE, or (4)
SIOCDEVEMANSIPATE ioctl request, which allows local  users to bypass intended
capability restrictions.    CVE-2008-4554  The do_splice_from function in
fs/splice.c in the Linux kernel before 2.6.27  does not reject file descriptors
that have the O_APPEND flag set, which allows  local users to bypass append mode
and make arbitrary changes to other locations  in the file.    CVE-2008-4576
sctp in Linux kernel before 2.6.25.18 allows remote attackers to cause a denial
of service (OOPS) via an INIT-ACK that states the peer does not support AUTH,
which causes the sctp_process_init function to clean up active transports and
triggers the OOPS when the T1-Init timer expires.      Also fixes these bugs
reported against Fedora 9:  465873 - kernel build-id note corruption  466303 -
IPSec kernel lockup.  464613 - 11143 unconditional linker option
arch/powerpc/lib/crtsavres.o causes external module buildfailure  463034 -
[sata_nv swncq] kernel 2.6.26.3-29 raid errors: "md: super_written gets
error=-5, uptodate=0"  460550 - Insert key does not work on console since 2.6.26
438606 - at76 stops working with port to mac80211  466511 - Kernel crash when
using openswan  462919 - kernel 2.6.26.3-19.fc9.x86_64 TT-budget C-1500 DVB card
is not longer working  462178 - PCMCIA CF adaptor causes kernel hang at
"Starting UDEV:"
