1) Problem Description and Brief Discussion

This update of the openSUSE 11.3 kernel brings the kernel to version
2.6.34.4 and contains a lot of bug and security fixes

CVE-2010-3110: Missing bounds checks in several ioctls of the Novell
Client novfs /proc interface allowed unprivileged local users to
crash the kernel or even execute code in kernel context. The affected
module is only loaded when the Novell Client stack is configured.

CVE-2010-2524: A malicious local user could fill the cache used by
CIFS do perform dns lookups with chosen data, therefore tricking the
kernel into mounting a wrong CIFS server.

CVE-2010-2798: A local user could trigger a NULL dereference on a gfs2
file system.

CVE-2010-2537: A local user could overwrite append-only files on a
btrfs file system.

CVE-2010-2538: A local user could read kernel memory of a btrfs
file system.

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

to apply the update, replacing 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

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

gpg: Signature made using RSA key ID 3D25D3D9
gpg: Good signature from "SuSE Security Team "

where 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

to verify the signature of the package, replacing 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-announce@opensuse.org
- SUSE's announce-only mailing list.
Only SUSE's security announcements are sent to this list.
