1) Problem Description and Brief Discussion
This update fixes several security issues and lots of bugs in the
openSUSE 11.1 kernel.
The Linux kernel on openSUSE 11.1 was updated to the stable version
2.6.27.19 and is also now at the same kernel as we are planning to
ship with SUSE Linux Enterprise (Server/Desktop) 11.
This update introduces kABI changes, so all kernel module packages
also need to be rebuilt and reapplied. Rebuilt NVIDIA KMPs already
are provided by NVIDIA, ATI and Madwifi KMPs will follow soon.
Following security issues are fixed:
CVE-2008-5079: net/atm/svc.c in the ATM subsystem in the Linux kernel
allows local users to cause a denial of service (kernel infinite loop)
by making two calls to svc_listen for the same socket, and then reading
a /proc/net/atm/*vc file, related to corruption of the vcc table.
CVE-2008-5700: libata in the Linux kernel does not set minimum timeouts
for SG_IO requests, which allows local users to cause a denial of
service (Programmed I/O mode on drives) via multiple simultaneous
invocations of an unspecified test program.
CVE-2008-5702: Buffer underflow in the ibwdt_ioctl function in
drivers/watchdog/ib700wdt.c in the Linux kernel might allow local users to have an unknown impact via a certain /dev/watchdog WDIOC_SETTIMEOUT
IOCTL call.
CVE-2009-0028: A minor signal handling vulnerability was fixed,
where a child could send his parent a arbitrary signal.
CVE-2009-0029: The ABI in the Linux kernel on s390, PowerPC, sparc64,
and MIPS 64-bit platforms requires that a 32-bit argument in a 64-bit
register was properly sign extended when sent from a user-mode
application, but cannot verify this, which allows local users to
cause a denial of service (crash) or possibly gain privileges via a
crafted system call.
CVE-2009-0031: Memory leak in the keyctl_join_session_keyring function
(security/keys/keyctl.c) in Linux kernel allows local users to cause
a denial of service (kernel memory consumption) via unknown vectors related to a "missing kfree."
CVE-2009-0065: Buffer overflow in net/sctp/sm_statefuns.c in the
Stream Control Transmission Protocol (sctp) implementation in the
Linux kernel allows remote attackers to have an unknown impact via
an FWD-TSN (aka FORWARD-TSN) chunk with a large stream ID.
CVE-2009-0269:fs/ecryptfs/inode.c in the eCryptfs subsystem in the
Linux kernel before allows local users to cause a denial of service
(fault or memory corruption), or possibly have unspecified other
impact, via a readlink call that results in an error, leading to use
of a -1 return value as an array index.
CVE-2009-0322: drivers/firmware/dell_rbu.c in the Linux kernel allows
local users to cause a denial of service (system crash) via a read
system call that specifies zero bytes from the (1) image_type or (2)
packet_size file in /sys/devices/platform/dell_rbu/.
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@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
