1) Solved Security Vulnerabilities

To avoid flooding mailing lists with SUSE Security Announcements for minor
issues, SUSE Security releases weekly summary reports for the low profile
vulnerability fixes. The SUSE Security Summary Reports do not list or
download URLs like the SUSE Security Announcements that are released for
more severe vulnerabilities.

Fixed packages for the following incidents are already available on our FTP
server and via the YaST Online Update.

- OpenOffice_org
This update of OpenOffice.org fixes potential buffer overflow in EMF
parser code (enhwmf.cxx, emfplus.cxx). Additionally Secunia reported an
integer underflow (CVE-2009-0200) and a buffer overflow (CVE-2009-0201)
that could be triggered while parsing Word documents.

Also provides the maintenance update to OpenOffice.org-3.1.1.

Details about all upstream changes can be found at
http://development.openoffice.org/releases/3.1.1.html

Released for product: openSUSE 10.3-11.1, NLD9, SLE10, SLE11

- dnsmasq
This update fixes a buffer overflow in the TFTP server code of dnsmasq.
Please note that the TFTP server is disabled by default.

Released for product: openSUSE 10.3-11.1, SLE11

- gnutls
This update of gnutls improves the verification of the domain/subject
names in a SSL certificate. CVE-2009-2730 has been assigned to this
issue.

Released for product: openSUSE 10.3-11.1, SLE10, SLE11

- ia32el
A 32bit x86 user program could crash the Itanium IA64 kernel in the
IA 32 (Intel 32bit) emulation. (CVE-2009-2707)

Released for product: SLE10

Updateing IA32EL to 7042_7022, the same version as shipped on SLES 10
SP3, fixes this problem.

- ib-bonding-kmp-rt/kernel-rt/ofed
This patch updates the SLERT10 SP2 kernel to Update 7 to address
multiple issues:

- Lots of HR Timer fixes and improvements.

The complete list of changes can be seen in the rpm changelog.

It also fixes several security issues, some of the critical:

CVE-2009-2692: A missing NULL pointer check in the socket sendpage
function can be used by local attackers to gain root privileges.

CVE-2009-2406: A kernel stack overflow when mounting eCryptfs filesystems
in parse_tag_11_packet() was fixed. Code execution might be possible
of ecryptfs is in use.

CVE-2009-2407: A kernel heap overflow when mounting eCryptfs filesystems
in parse_tag_3_packet() was fixed. Code execution might be possible
of ecryptfs is in use.

Released for product: SLERT10

- libxml
This update of libxml does not use pointers after they were freed
anymore. (CVE-2009-2416)
Additionally a stack-based buffer overflow was fixed while parsing the
root XML document. (CVE-2009-2414)

Released for product: openSUSE 10.3-11.1, SLES9, SLE10, SLE11

- opera
Opera version 10 includes at least security fixes for an XML
denial-of-service bug (CVE-2009-1234) and the "SSL tampering" attack
(CVE-2009-2059, CVE-2009-2063, CVE-2009-2067, CVE-2009-2070).

Released for product: openSUSE 10.3-11.1

- perl-IO-Socket-SSL
This update of perl-IO-Socket-SSL improves the hostname checking of the
SSL certificate. (CVE-2009-3024)

Released for product: openSUSE 11.1, SLE11

- xen
xend did not properly enforce access control of the xenstore
directory tree, therefore allowing guest VM's to write there.
This could lead to security problems if other applications such as
libvirt are not prepared for untrusted data in the xenstore
directory (CVE-2008-4405).

Released for product: openSUSE 11.0

3) 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 containing 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@xxxxxxx>"

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 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 <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@xxxxxxx 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 included at the end of this
announcement.

- SUSE runs two security mailing lists to which any interested party may
subscribe:

opensuse-security@xxxxxxxxxxxx
- General Linux and SUSE security discussion.
All SUSE security announcements are sent to this list.
To subscribe, send an e-mail to
<opensuse-security+subscribe@xxxxxxxxxxxx>.

opensuse-security-announce@xxxxxxxxxxxx
- SUSE's announce-only mailing list.
Only SUSE's security announcements are sent to this list.
To subscribe, send an e-mail to
<opensuse-security-announce+subscribe@xxxxxxxxxxxx>.

=====================================================================
SUSE's security contact is <security@xxxxxxxx> or <security@xxxxxxx>.
The <security@xxxxxxx> public key is listed below.
