1) Problem Description and Brief Discussion
This update fixes a several security issues and various bugs in the
SUSE Linux Enterprise 10 SP 2 kernel.
Following security issues were fixed:
CVE-2009-3547: A race condition during pipe open could be used by
local attackers to elevate privileges.
CVE-2009-2910: On x86_64 systems an information leak of high register
contents (upper 32bit) was fixed.
CVE-2009-3238: The randomness of the ASLR methods used in the kernel
was increased.
CVE-2009-1192: A information leak from the kernel due to uninitialized
memory in AGP handling was fixed.
CVE-2009-2909: A signed comparison in the ax25 sockopt handler
was fixed which could be used to crash the kernel or potentially
execute code.
CVE-2009-2848: The execve function in the Linux kernel did not properly
clear the current->clear_child_tid pointer, which allows local
users to cause a denial of service (memory corruption) or possibly
gain privileges via a clone system call with CLONE_CHILD_SETTID or
CLONE_CHILD_CLEARTID enabled, which is not properly handled during
thread creation and exit.
CVE-2009-3002: Fixed various socket handler getname leaks, which
could disclose memory previously used by the kernel or other userland
processes to the local attacker.
CVE-2009-1633: Multiple buffer overflows in the cifs subsystem in the
Linux kernel allow remote CIFS servers to cause a denial of service
(memory corruption) and possibly have unspecified other impact via (1)
a malformed Unicode string, related to Unicode string area alignment
in fs/cifs/sess.c; or (2) long Unicode characters, related to
fs/cifs/cifssmb.c and the cifs_readdir function in fs/cifs/readdir.c.
Also see the RPM changelog for more changes.
2) Solution or Work-Around
There is no known workaround, please install the update packages.
3) Special Instructions and Notes
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:

5) Pending Vulnerabilities, Solutions, and Work-Arounds:
- Pending kernels for CVE-2009-3547 problem
SUSE Linux Enterprise 10 SP3 kernels will be released tomorrow.
SUSE Linux Enterprise 9 kernels had another QA failure and so will
be released approximately begin of next week.
openSUSE 11.0, 11.1 and SUSE Linux Enterprise 11 kernels have
"mmap_min_addr" protection by default and will be released in their
regular release cycles. (Probably around end of November).

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 "
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.
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.
