    value:
"An integer overflow was discovered in the do_replace() function. A
local user process with the CAP_NET_ADMIN capability could exploit
this to execute arbitrary commands with full root privileges. However,
none of Ubuntu's supported packages use this capability with any
non-root user, so this only affects you if you use some third party
software like the OpenVZ virtualization system. (CVE-2006-0038)

On EMT64 CPUs, the kernel did not properly handle uncanonical return
addresses. A local user could exploit this to trigger a kernel crash.
(CVE-2006-0744)

Al Viro discovered a local Denial of Service in the sysfs write buffer
handling. By writing a block with a length exactly equal to the
processor's page size to any writable file in /sys, a local attacker
could cause a kernel crash. (CVE-2006-1055)

Jan Beulich discovered an information leak in the handling of
registers for the numeric coprocessor when running on AMD processors.
This allowed processes to see the coprocessor execution state of other
processes, which could reveal sensitive data in the case of
cryptographic computations. (CVE-2006-1056)

Marcel Holtmann discovered that the sys_add_key() did not check that a
new user key is added to a proper keyring. By attempting to add a key
to a normal user key (which is not a keyring), a local attacker could
exploit this to crash the kernel. (CVE-2006-1522)

Ingo Molnar discovered that the SCTP protocol connection tracking
module in netfilter got stuck in an infinite loop on certain empty
packet chunks. A remote attacker could exploit this to cause the
computer to hang. (CVE-2006-1527)

The SCSI I/O driver did not correctly handle the VM_IO flag for memory
mapped pages used for data transfer. A local user could exploit this
to cause a kernel crash. (CVE-2006-1528)

The choose_new_parent() contained obsolete debugging code. A local
user could exploit this to cause a kernel crash. (CVE-2006-1855)

Kostik Belousov discovered that the readv() and writev() functions did
not query LSM modules for access permission. This could be exploited
to circumvent access restrictions defined by LSM modules such as
SELinux or AppArmor. (CVE-2006-1856)

The SCTP driver did not properly verify certain parameters when
receiving a HB-ACK chunk. By sending a specially crafted packet to an
SCTP socket, a remote attacker could exploit this to trigger a buffer
overflow, which could lead to a crash or possibly even arbitrary code
execution. (CVE-2006-1857)

The sctp_walk_params() function in the SCTP driver incorrectly used
rounded values for bounds checking instead of the precise values. By
sending a specially crafted packet to an SCTP socket, a remote
attacker could exploit this to crash the kernel. (CVE-2006-1858)

Bjoern Steinbrink reported a memory leak in the __setlease() function.
A local attacker could exploit this to exhaust kernel memory and
render the computer unusable (Denial of Service). (CVE-2006-1859)

Daniel Hokka Zakrisson discovered that the lease_init() did not
properly handle locking. A local attacker could exploit this to cause
a kernel deadlock (Denial of Service). (CVE-2006-1860)

Mark Moseley discovered that the CIFS file system driver did not
filter out '..\\' path components. A local attacker could exploit this
to break out of a chroot environment on a mounted SMB share.
(CVE-2006-1863) The same vulnerability applies to the older smb file
system. (CVE-2006-1864)

Hugh Dickins discovered that the mprotect() function allowed an user
to change a read-only shared memory attachment to become writable,
which bypasses IPC (inter-process communication) permissions.
(CVE-2006-2071)

The SCTP (Stream Control Transmission Protocol) driver triggered a
kernel panic on unexpected packets while the session was in the CLOSED
state, instead of silently ignoring the packets. A remote attacker
could exploit this to crash the computer. (CVE-2006-2271)

The SCTP driver did not handle control chunks if they arrived in
fragmented packets. By sending specially crafted packets to an SCTP
socket, a remote attacker could exploit this to crash the target
machine. (CVE-2006-2272)

The SCTP driver did not correctly handle packets containing more than
one DATA fragment. By sending specially crafted packets to an SCTP
socket, a remote attacker could exploit this to crash the target
machine. (CVE-2006-2274)

The SCTP driver did not correcly buffer incoming packets. By sending a
large number of small messages to a receiver application that cannot
process the messages quickly enough, a remote attacker could exploit
this to cause a deadlock in the target machine (Denial of Service).
(CVE-2006-2275)

Patrick McHardy discovered that the snmp_trap_decode() function did
not correctly handle memory allocation in some error conditions. By
sending specially crafted packets to a machine which uses the SNMP
network address translation (NAT), a remote attacker could exploit
this to crash that machine. (CVE-2006-2444)

In addition, the Ubuntu 6.06 LTS update fixes a range of bugs.

"A number of vulnerabilities were discovered and corrected in the Linux
2.6 kernel :

Prior to Linux kernel 2.6.16.5, the kernel does not properly handle
uncanonical return addresses on Intel EM64T CPUs which causes the
kernel exception handler to run on the user stack with the wrong GS
(CVE-2006-0744).

The selinux_ptrace logic hooks in SELinux for 2.6.6 allow local users
with ptrace permissions to change the tracer SID to an SID of another
process (CVE-2006-1052).

Prior to 2.6.16, the ip_push_pending_frames function increments the IP
ID field when sending a RST after receiving unsolicited TCP SYN-ACK
packets, which allows a remote attacker to conduct an idle scan
attack, bypassing any intended protection against such an attack
(CVE-2006-1242).

In kernel 2.6.16.1 and some earlier versions, the sys_add_key function
in the keyring code allows local users to cause a DoS (OOPS) via
keyctl requests that add a key to a user key instead of a keyring key,
causing an invalid dereference (CVE-2006-1522).

Prior to 2.6.16.8, the ip_route_input function allows local users to
cause a DoS (panic) via a request for a route for a multicast IP
address, which triggers a null dereference (CVE-2006-1525).

Prior to 2.6.16.13, the SCTP-netfilter code allows remote attackers to
cause a DoS (infinite loop) via unknown vectors that cause an invalid
SCTP chunk size to be processed (CVE-2006-1527).

Prior to 2.6.16, local users can bypass IPC permissions and modify a
read-only attachment of shared memory by using mprotect to give write
permission to the attachment (CVE-2006-2071).

Prior to 2.6.17, the ECNE chunk handling in SCTP (lksctp) allows
remote attackers to cause a DoS (kernel panic) via an unexpected
chucnk when the session is in CLOSED state (CVE-2006-2271).

Prior to 2.6.17, SCTP (lksctp) allows remote attacker to cause a DoS
(kernel panic) via incoming IP fragmented COOKIE_ECHO and HEARTBEAT
SCTP control chunks (CVE-2006-2272).

In addition to these security fixes, other fixes have been included
such as :

  - fix a scheduler deadlock

    - Yenta oops fix

    - ftdi_sio: adds support for iPlus devices

    - enable kprobes on i386 and x86_64

    - avoid a panic on bind mount of autofs owned directory

    - fix a kernel OOPs when booting with 'console=ttyUSB0'
      but without a USB-serial dongle plugged in

  - make dm-mirror not issue invalid resync requests

    - fix media change detection on scsi removable devices

    - add support for the realtek 8168 chipset

    - update hfsplus driver to 2.6.16 state

    - backport 'Gilgal' support from e1000 7.0.33

    - selected ACPI video fixes

    - update 3w-9xxx to 2.26.02.005 (9550SX support)

    - fix a deadlock in the ext2 filesystem

    - fix usbserial use-after-free bug

    - add i945GM DRI support

    - S3 resume fixes

    - add ECS PF22 hda model support

    - SMP suspend

    - CPU hotplug

    - miscellaneous AGP fixes

    - added sata-suspend patch for 2.6.12 for Napa platform

The provided packages are patched to fix these vulnerabilities. All
users are encouraged to upgrade to these updated kernels.

As well, updated mkinitrd and bootsplash packages are provided to fix
minor issues; users should upgrade both packages prior to installing a
new kernel.

"Updated kernel packages that fix several security issues in the Red
Hat Enterprise Linux 4 kernel are now available.

This security advisory has been rated as having important security
impact by the Red Hat Security Response Team.

The Linux kernel handles the basic functions of the operating system.

These new kernel packages contain fixes for the security issues

(crash) upon return from certain system calls (CVE-2006-0741 and
CVE-2006-0744, important)

* a flaw in the keyring implementation that allowed a local user to
cause a denial of service (OOPS) (CVE-2006-1522, important)

* a flaw in IP routing implementation that allowed a local user to
cause a denial of service (panic) via a request for a route for a
multicast IP (CVE-2006-1525, important)

* a flaw in the SCTP-netfilter implementation that allowed a remote
user to cause a denial of service (infinite loop) (CVE-2006-1527,
important)

* a flaw in the sg driver that allowed a local user to cause a denial
of service (crash) via a dio transfer to memory mapped (mmap) IO space
(CVE-2006-1528, important)

* a flaw in the threading implementation that allowed a local user to
cause a denial of service (panic) (CVE-2006-1855, important)

* two missing LSM hooks that allowed a local user to bypass the LSM by
using readv() or writev() (CVE-2006-1856, moderate)

* a flaw in the virtual memory implementation that allowed local user
to cause a denial of service (panic) by using the lsof command
(CVE-2006-1862, important)

* a directory traversal vulnerability in smbfs that allowed a local
user to escape chroot restrictions for an SMB-mounted filesystem via
'..\\' sequences (CVE-2006-1864, moderate)

* a flaw in the ECNE chunk handling of SCTP that allowed a remote user
to cause a denial of service (panic) (CVE-2006-2271, moderate)

* a flaw in the handling of COOKIE_ECHO and HEARTBEAT control chunks
of SCTP that allowed a remote user to cause a denial of service
(panic) (CVE-2006-2272, moderate)

* a flaw in the handling of DATA fragments of SCTP that allowed a
remote user to cause a denial of service (infinite recursion and
crash) (CVE-2006-2274, moderate)

All Red Hat Enterprise Linux 4 users are advised to upgrade their
kernels to the packages associated with their machine architectures
and configurations as listed in this erratum."
