______________________________________________________________________________
1) Problem Description and Brief Discussion
The Linux kernel on the SUSE Linux Enterprise 10 Service Pack 1 line
of products was updated to fix quite a number of security problems:
CVE-2007-6282: A remote attacker could crash the IPSec/IPv6 stack
by sending a bad ESP packet. This requires the host to be able to
receive such packets (default filtered by the firewall).
CVE-2008-2136: A problem in SIT IPv6 tunnel handling could be used
by remote attackers to immediately crash the machine.
CVE-2008-1615: On x86_64 a denial of service attack could be used by
local attackers to immediately panic / crash the machine.
CVE-2007-6206: An information leakage during core dumping of root
processes was fixed.
CVE-2008-1669: Fixed a SMP ordering problem in fcntl_setlk could
potentially allow local attackers to execute code by timing file
locking.
CVE-2008-1375: Fixed a dnotify race condition, which could be used
by local attackers to potentially execute code.
CVE-2007-5500: A ptrace bug could be used by local attackers to hang
their own processes indefinitely.
CVE-2008-1367: Clear the "direction" flag before calling signal
handlers. For specific not yet identified programs under specific
timing conditions this could potentially have caused memory corruption
or code execution.
CVE-2007-6151: The isdn_ioctl function in isdn_common.c allowed local
users to cause a denial of service via a crafted ioctl struct in
which ioctls is not null terminated, which triggers a buffer overflow.
Non security related changes:
OCFS2 was updated to version v1.2.9-1-r3100.
Also a huge number of bugs were fixed. Please refer to the RPM
changelog for a detailed list.
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 updated packages.
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-at-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-at-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-at-opensuse.org
- SUSE's announce-only mailing list.
Only SUSE's security announcements are sent to this list.
