______________________________________________________________________________

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.

- powerdns spoofing problems

The PowerDNS packages were updated to offer better spoofing
resistance by not ignoring invalid queries. (CVE-2008-3337)

This problem affected only openSUSE 10.2 - 11.0.


- dnsmasq spoofing problems

The DNS server dnsmasq was changed to use random UDP source ports
and a random TRXID now. (CVE-2008-1447)

This problem only affected openSUSE 10.2 - 11.0.


- python multiple problems

The scripting language python was updated to fix several security
vulnerabilities. (CVE-2008-1679,CVE-2008-1887, CVE-2008-3143,
CVE-2008-3142, CVE-2008-3144, CVE-2008-2315, CVE-2008-2316)

All SUSE Linux products received updated python packages.


- mailman cross site scripting

The mailing list manager mailman was updated to fix a
cross-site-scripting bug (CVE-2008-0564) and a mistake in
translation.

All distributions containing mailman received updated packages.


- ruby multiple problems

The scripting language ruby was updated to fix:
- a possible information leakage (CVE-2008-1145)
- a directory traversal bug (CVE-2008-1891) in WEBrick
- various memory corruptions and integer overflows in array and
string handling (CVE-2008-2662, CVE-2008-2663, CVE-2008-2664,
CVE-2008-2725, CVE-2008-2726, CVE-2008-2727, CVE-2008-2728)

ruby was updated on all SUSE Linux products.


- Opera 9.52

Opera was upgraded to version 9.52 to fix possible security
vulnerabilities.

Please see http://www.opera.com/docs/changelogs/linux/952/ for
more details.


- neon NULL pointer problem

The helper library neon was updated to fix a NULL pointer dereference
in the digest authentication code. (CVE-2008-3746)

neon was updated on all affected distributions.


- rxvt-unicode session hijacking

Using rxvt-unicode it was possible to open a terminal on :0 when
the environment variable was not set.

This could be exploited by local users to hijack X11 connections
(CVE-2008-1142).

rxvt-unicode was updated on openSUSE 10.2-11.0.


- perl multiple problems

Several problems were fixed in the scripting language perl.

Specially crafted regular expressions could crash perl
(CVE-2008-1927).

Insufficient symlink checks in the File::Path could result in wrong
file permissions (CVE-2008-2827).

Additionally problem in the CGI module was fixed that could result
in an endless loop if uploads were canceled.


- Wireshark / ethereal multiple security problems

Various vulnerabilities have been fixed in ethereal and wireshark:
CVE-2008-3137, CVE-2008-3138, CVE-2008-3139,
CVE-2008-3140, CVE-2008-3141, CVE-2008-3145
and CVE-2008-3146. Those could be potentially used to crash
wireshark or potentially execute code.

Updates have been released for all SUSE Linux distributions.


- namazu cross site scripting

The indexing engine namazu was upgraded to fix a UTF-7
cross-site-scripting vulnerability. (CVE-2008-1468)

namazu was updated on all products containing it.


- gnome-screensaver clipboard disclosure

gnome-screensaver was updated to disallows local users to
read the contents of the clipboard for a locked screen using
ctrl-v. (CVE-2007-6389)

Updates have been released for openSUSE 10.3, other distributions
were not affected.


- MySQL security problems

The database server MySQL was updated to fix a security problem:

CVE-2008-2079: MySQL allowed local users to bypass certain privilege
checks by calling CREATE TABLE on a MyISAM table with modified (1)
DATA DIRECTORY or (2) INDEX DIRECTORY arguments that are within
the MySQL home data directory, which can point to tables that are
created in the future.

CVE-2006-7232: sql_select.cc in MySQL 5.0.x before 5.0.32 and 5.1.x
before 5.1.14 allows remote authenticated users to cause a denial of
service (crash) via an EXPLAIN SELECT FROM on the INFORMATION_SCHEMA
table, as originally demonstrated using ORDER BY.

MySQL was updated on all SUSE Linux distributions.

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.

<opensuse-security-announce+subscribe@xxxxxxxxxxxx>.
