1) Problem Description and Brief Discussion

This security update of the SUSE Linux Enterprise 11 GA and openSUSE
11.1 kernel updates the kernel to 2.6.27.54 and fixes various security
issues and other bugs.

The SUSE Linux Enterprise Server 11 kernel was released last week,
the openSUSE 11.1 kernel with the same source base yesterday.

Following security issues were fixed:
CVE-2010-3310: Multiple integer signedness errors in net/rose/af_rose.c
in the Linux kernel allowed local users to cause a denial of service
(heap memory corruption) or possibly have unspecified other impact
via a rose_getname function call, related to the rose_bind and
rose_connect functions.

CVE-2010-2955: A kernel information leak via the WEXT ioctl was fixed.

CVE-2010-3080: A double free in an alsa error path was fixed, which
could lead to kernel crashes.

CVE-2010-3078: Fixed a kernel information leak in the xfs filesystem.

CVE-2010-3296: Fixed a kernel information leak in the cxgb3 driver.

CVE-2010-3297: Fixed a kernel information leak in the net/eql driver.

CVE-2010-2954: The irda_bind function in net/irda/af_irda.c in the
Linux kernel did not properly handle failure of the irda_open_tsap
function, which allowed local users to cause a denial of service
(NULL pointer dereference and panic) and possibly have unspecified
other impact via multiple unsuccessful calls to bind on an AF_IRDA
(aka PF_IRDA) socket.

CVE-2010-2946: The 'os2' xattr namespace on the jfs filesystem could
be used to bypass xattr namespace rules.

CVE-2010-2942: Fixed a kernel information leak in the net scheduler
code.

CVE-2010-3015: Integer overflow in the ext4_ext_get_blocks function
in fs/ext4/extents.c in the Linux kernel allowed local users to cause
a denial of service (BUG and system crash) via a write operation on
the last block of a large file, followed by a sync operation.

CVE-2010-2803: The drm_ioctl function in drivers/gpu/drm/drm_drv.c
in the Direct Rendering Manager (DRM) subsystem in the Linux kernel
allowed local users to obtain potentially sensitive information from
kernel memory by requesting a large memory-allocation amount.

CVE-2010-2798: The gfs2_dirent_find_space function in fs/gfs2/dir.c
in the Linux kernel used an incorrect size value in calculations
associated with sentinel directory entries, which allowed local users
to cause a denial of service (NULL pointer dereference and panic) and
possibly have unspecified other impact by renaming a file in a GFS2
filesystem, related to the gfs2_rename function in fs/gfs2/ops_inode.c.

2) Solution or Work-Around

There is no workaround, please install the fixed packages.

3) Special Instructions and Notes

Please reboot the machine after the update.

4) Package Location and Checksums

The preferred method for installing security updates is to use the YaST
"Online Update" module or the "zypper" commandline tool. The package and
patch management stack will detect which updates are required and
automatically perform 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.
To subscribe, send an e-mail to
