1) Problem Description and Brief Discussion
This update fixes lots of bugs and some security issues in the SUSE
Linux Enterprise 10 SP 3 kernel.
CVE-2009-4020: Stack-based buffer overflow in the hfs subsystem in the
Linux kernel allows remote attackers to have an unspecified impact
via a crafted Hierarchical File System (HFS) filesystem, related to
the hfs_readdir function in fs/hfs/dir.c.
CVE-2010-0410: drivers/connector/connector.c in the Linux kernel
allows local users to cause a denial of service (memory consumption and
system crash) by sending the kernel many NETLINK_CONNECTOR messages.
CVE-2009-3556: A configuration value in the qla2xxx driver in the
Linux kernel when N_Port ID Virtualization (NPIV) hardware is used,
sets world-writable permissions for the (1) vport_create and (2)
vport_delete files under /sys/class/scsi_host/, which allows local
users to make arbitrary changes to SCSI host attributes by modifying
these files.
CVE-2010-1083: A kernel information leak using user space USB devices
could be used by local attackers with USB access to read recently
freed kernel memory.
CVE-2010-1086: A ULE decapsulation denial of service problem in DVB
drivers was fixed that could be triggered by invalid DVB data packets.
CVE-2010-1088: A NFS denial of service by following "automount"
symlinks was fixed.
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.
Our maintenance customers are notified individually. The packages are
offered for installation from the maintenance web:

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.
