1) Problem Description and Brief Discussion
This kernel update fixes the following critical security problem:
- CVE-2008-0600: A local privilege escalation was found in the
vmsplice_pipe system call, which could be used by local attackers
to gain root access.
This bug affects the following products:
- openSUSE 10.2 and 10.3
- SUSE Linux Enterprise Realtime 10 (SP1)
Fixed packages have been released for openSUSE 10.2 and 10.3.
For SUSE Linux Enterprise Realtime 10 packages are being prepared
currently.
Since this problem affects Linux kernels starting with 2.6.17 and
vmsplice was not back-ported, no older products are affected.
- SUSE Linux Enterprise Server 8, 9, and 10: Not affected.
- SUSE Linux Enterprise Desktop 10: Not affected.
- Novell Linux Desktop 9: Not affected.
- SUSE Linux 10.1: Not affected.
Following minor security problems were fixed additionally:
- CVE-2007-6206: Core dumps from root might be accessible to the
wrong owner. This was fixed for openSUSE 10.3 only.
- 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 iocts is not null terminated, which triggers a
buffer overflow. This problem was fixed for openSUSE 10.2.
And the following bugs were fixed for openSUSE 10.3 (numbers are
https://bugzilla.novell.com/ references):
- Update to minor kernel version 2.6.22.17
- networking bugfixes
- contains the following patches which were removed:
- patches.arch/acpica-psd.patch
- patches.fixes/invalid-semicolon
- patches.fixes/nopage-range-fix.patch
- patches.arch/acpi_thermal_blacklist_add_r50p.patch:
Avoid critical temp shutdowns on specific ThinkPad R50p
(https://bugzilla.novell.com/show_bug.cgi?id=333043).
- patches.rt/megasas_IRQF_NODELAY.patch: Convert megaraid SAS
IRQ to non-threaded IRQ (337489).
- patches.drivers/libata-implement-force-parameter added to
series.conf.
- patches.xen/xen3-fixup-arch-i386: Xen3 i386 build fixes.
- patches.xen/xenfb-module-param: Re: Patching Xen virtual
framebuffer.
2) Solution or Work-Around
There is no known workaround, please install the update packages.
3) Special Instructions and Notes
The machine needs to be rebooted to make the changes active.
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 <file.rpm>
to apply the update, replacing <file.rpm> 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 <file>
replacing <file> with the name of the file where you saved the
announcement. The output for a valid signature looks like:
gpg: Signature made <DATE> using RSA key ID 3D25D3D9
gpg: Good signature from "SuSE Security Team
<security@suse.de>"
where <DATE> 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.
There are two verification methods that can be used independently from
each other to prove the authenticity of a downloaded file or RPM package:
1) Using the internal gpg signatures of the rpm package
2) MD5 checksums as provided in this announcement
1) The internal rpm package signatures provide an easy way to verify the
authenticity of an RPM package. Use the command
rpm -v --checksig <file.rpm>
to verify the signature of the package, replacing <file.rpm> 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.
2) If you need an alternative means of verification, use the md5sum
command to verify the authenticity of the packages. Execute the command
md5sum <filename.rpm>
after you downloaded the file from a SUSE FTP server or its mirrors.
Then compare the resulting md5sum with the one that is listed in the
SUSE security announcement. Because the announcement containing the
checksums is cryptographically signed (by security@suse.de), the
checksums show proof of the authenticity of the package if the
signature of the announcement is valid. Note that the md5 sums
published in the SUSE Security Announcements are valid for the
respective packages only. Newer versions of these packages cannot be
verified.
