______________________________________________________________________________

1) Problem Description and Brief Discussion

This update fixes various security issues and several bugs in the
openSUSE 11.0 kernel.

The kernel was also updated to the stable version 2.6.25.20,
including its bugfixes.

Following security issues were fixed:

CVE-2008-5702: Buffer underflow in the ibwdt_ioctl function in
drivers/watchdog/ib700wdt.c might allow local users to have an unknown
impact via a certain /dev/watchdog WDIOC_SETTIMEOUT IOCTL call.

CVE-2008-5700: libata did not set minimum timeouts for SG_IO requests,
which allows local users to cause a denial of service (Programmed
I/O mode on drives) via multiple simultaneous invocations of an
unspecified test program.

CVE-2008-5079: net/atm/svc.c in the ATM subsystem allowed local users
to cause a denial of service (kernel infinite loop) by making two calls
to svc_listen for the same socket, and then reading a /proc/net/atm/*vc
file, related to corruption of the vcc table.

CVE-2008-5300: Linux kernel 2.6.28 allows local users to cause a
denial of service ("soft lockup" and process loss) via a large
number
of sendmsg function calls, which does not block during AF_UNIX garbage
collection and triggers an OOM condition, a different vulnerability
than CVE-2008-5029.

CVE-2008-5029: The __scm_destroy function in net/core/scm.c makes
indirect recursive calls to itself through calls to the fput function,
which allows local users to cause a denial of service (panic) via
vectors related to sending an SCM_RIGHTS message through a UNIX domain
socket and closing file descriptors.

CVE-2008-4933: Buffer overflow in the hfsplus_find_cat function in
fs/hfsplus/catalog.c allowed attackers to cause a denial of service
(memory corruption or system crash) via an hfsplus filesystem
image with an invalid catalog namelength field, related to the
hfsplus_cat_build_key_uni function.

CVE-2008-5025: Stack-based buffer overflow in the hfs_cat_find_brec
function in fs/hfs/catalog.c allowed attackers to cause a denial of
service (memory corruption or system crash) via an hfs filesystem
image with an invalid catalog namelength field, a related issue to
CVE-2008-4933.

CVE-2008-5182: The inotify functionality might allow local users to
gain privileges via unknown vectors related to race conditions in
inotify watch removal and umount.

CVE-2008-3831: The i915 driver in drivers/char/drm/i915_dma.c does not
restrict the DRM_I915_HWS_ADDR ioctl to the Direct Rendering Manager
(DRM) master, which allows local users to cause a denial of service
(memory corruption) via a crafted ioctl call, related to absence of
the DRM_MASTER and DRM_ROOT_ONLY flags in the ioctls configuration.

CVE-2008-4554: The do_splice_from function in fs/splice.c did 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.

2) Solution or Work-Around

There is no known workaround, please install the update packages.

3) Special Instructions and Notes

Please reboot the machine after installing the update.

4) Package Location and Checksums

The preferred method for installing security updates is to use the YaST
Online Update (YOU) tool. YOU detects which updates are required and
automatically performs the necessary steps to verify and install them.
Alternatively, download the update packages for your distribution manually
and verify their integrity by the methods listed in Section 6 of this
announcement. Then install the packages using the command

rpm -Fhv <file.rpm>

to apply the update, replacing <file.rpm> with the filename of the
downloaded RPM package.

6) Authenticity Verification and Additional Information

- Announcement authenticity verification:

SUSE security announcements are published via mailing lists and on Web
sites. The authenticity and integrity of a SUSE security announcement is
guaranteed by a cryptographic signature in each announcement. All SUSE
security announcements are published with a valid signature.

To verify the signature of the announcement, save it as text into a file
and run the command

gpg --verify <file>

replacing <file> with the name of the file where you saved the
announcement. The output for a valid signature looks like:

gpg: Signature made <DATE> using RSA key ID 3D25D3D9
gpg: Good signature from "SuSE Security Team
<security@suse.de>"

where <DATE> is replaced by the date the document was signed.

If the security team's key is not contained in your key ring, you can
import it from the first installation CD. To import the key, use the
command

gpg --import gpg-pubkey-3d25d3d9-36e12d04.asc

- Package authenticity verification:

SUSE update packages are available on many mirror FTP servers all over the
world. While this service is considered valuable and important to the free
and open source software community, the authenticity and the integrity of
a package needs to be verified to ensure that it has not been tampered
with.

The internal rpm package signatures provide an easy way to verify the
authenticity of an RPM package. Use the command

rpm -v --checksig <file.rpm>

to verify the signature of the package, replacing <file.rpm> with the
filename of the RPM package downloaded. The package is unmodified if it
contains a valid signature from build@suse.de with the key ID 9C800ACA.

This key is automatically imported into the RPM database (on
RPMv4-based distributions) and the gpg key ring of 'root' during
installation. You can also find it on the first installation CD and at
the end of this announcement.

- SUSE runs two security mailing lists to which any interested party may
subscribe:

opensuse-security@opensuse.org
- General Linux and SUSE security discussion.
All SUSE security announcements are sent to this list.
To subscribe, send an e-mail to
<opensuse-security+subscribe@opensuse.org>.

opensuse-security-announce@opensuse.org
- SUSE's announce-only mailing list.
Only SUSE's security announcements are sent to this list.
To subscribe, send an e-mail to
<opensuse-security-announce+subscribe@opensuse.org>.
