______________________________________________________________________________
1) Problem Description and Brief Discussion
This update of the openSUSE 11.2 kernel brings the kernel to version 2.6.31.12 and contains a lot of bug and security fixes.
CVE-2010-0299: The permission of the devtmpfs root directory was incorrectly 1777 (instead of 755). If it was used, local attackers could escalate privileges. (openSUSE 11.2 does not use this filesystem by default).
CVE-2009-3939: The poll_mode_io file for the megaraid_sas driver in the Linux kernel 2.6.31.6 and earlier has world-writable permissions, which allows local users to change the I/O mode of the driver by modifying this file.
CVE-2010-0007: ebtables was lacking a CAP_NET_ADMIN check, making it possible for local unprivileged attackers to modify the network bridge management.
CVE-2010-0003: An information leakage on fatal signals on x86_64 machines was fixed.
CVE-2009-4141: A race condition in fasync handling could be used by local attackers to crash the machine or potentially execute code.
CVE-2010-0006: The ipv6_hop_jumbo function in net/ipv6/exthdrs.c in the Linux kernel before 2.6.32.4, when network namespaces are enabled, allows remote attackers to cause a denial of service (NULL pointer dereference) via an invalid IPv6 jumbogram.
CVE-2009-4536: drivers/net/e1000/e1000_main.c in the e1000 driver in the Linux kernel 2.6.32.3 and earlier handles Ethernet frames that exceed the MTU by processing certain trailing payload data as if it were a complete frame, which allows remote attackers to bypass packet filters via a large packet with a crafted payload.
CVE-2009-4538: drivers/net/e1000e/netdev.c in the e1000e driver in the Linux kernel 2.6.32.3 and earlier does not properly check the size of an Ethernet frame that exceeds the MTU, which allows remote attackers to have an unspecified impact via crafted packets.
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.

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. To subscribe, send an e-mail to .
