1) Problem Description and Brief Discussion
The openSUSE 11.3 kernel was updated to version 2.6.34.7. The update fixes
lots of bugs and security issues.
A major regression in handling some USB Input devices (Mice and Keyboard)
introduced by the previous update was fixed.
We also fixed a lot of bugs in the ATH5K wireless driver.
Following security issues were fixed:
CVE-2010-3078: A XFS stack memory information disclosure was fixed.
CVE-2010-2954: A NULL pointer dereference in the IRDA stack was fixed,
which could lead to kernel crashes.
CVE-2010-2959: A local privilege escalation in the CAN bus protocol
module can_bcm was fixed.
CVE-2010-2942: Several memory leaks in the net scheduling code
were fixed.
CVE-2010-2803: Fixed kernel memory information leaks from DRM ioctls.
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.

5) Pending Vulnerabilities, Solutions, and Work-Arounds:
- Two new local privilege escalations in the Linux kernels
Two new local privilege escalations in the Linux kernel were reported
on Thursday. (CVE-2010-3081 and CVE-2010-3301).
CVE-2010-3301 only affects x86_64 (AMD64 and EM64T) systems, starting
with SUSE Linux Enterprise Server 11 or newer, and openSUSE 11.1
or newer.
CVE-2010-3081 affects bi arch capable kernels, which is x86_64, s390x
and ppc64 for SUSE, starting with SUSE Linux Enterprise Server 10
and newer, and openSUSE 11.1 and newer.
We are working on updates for those two new issues and hopefully
get to release them mid of next week.
Unfortunately a mitigating work-around is not available.
SUSE Linux Enterprise customers can request supported PTFs for
their kernel versions if waiting is not an option.

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.
