______________________________________________________________________________

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 md5 sums
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.

- RealPlayer security problem

A RealPlayer security problem was found where a specially crafted
.rm movie file could overflow a buffer and allow remote attackers
to execute code in the context of the user running the player.

We already released a fix with our previous RealPlayer security
update, check SUSE-SA:2005:059.

This is tracked by the Mitre CVE ID CVE-2005-2629.

- giflib,libungif denial of service attack / buffer overflows

The GIF processing libraries libungif and giflib were updated to
fix the following security issues:

- Specially crafted GIF files could crash applications
(CVE-2005-2974).

- Specially crafted GIF files could overwrite memory which
potentially allowed to execute arbitrary code (CVE-2005-3350).

This affects all SUSE Linux based products.

- snort overflow in back orifice preprocessor

A buffer overflow in snort's Back Orifice preprocessor code was
fixed. This bug can be exploited by remote attackers to execute
arbitrary code with the privileges of the snort daemon.

This is tracked by the Mitre CVE ID CVE-2005-3252.

All SUSE Linux based products containing snort were affected.

- clamav buffer overflows

The clamav virus scan engine was updated to version 0.87.1.
This upgrade fixes among other things the following security issues:

- clamav could be made to crash via a malformed DOC file
(CVE-2005-3239).

- a buffer overflow in the FSG decoder (CVE-2005-3303).

- clamav could run into an endless loop due to malformed CAB files
(CVE-2005-3500, CVE-2005-3501).

All SUSE Linux based distributions containing clamav were affected.

- jboss information disclosure

The default configuration of jboss allows disclosure of sensitive
information to remote users, by using a GET request with "%." to
reveal the local installation path, or "%" before a filename to
reveal the contents of this file.

We will not release updated packages for this. The jboss group
recommends disabling the RMIClassLoadingService webservice.

In all jboss-service.xml files you have, change this snippet:

lt;mbean code="org.jboss.web.WebService"
name="jboss:service=WebService"gt;
lt;attribute name="Port"gt;8083lt;/attributegt;
lt;!-- Should resources and non-EJB classes be downloadable --gt;
lt;attribute name="DownloadServerClasses"gt;truelt;/attributegt;
lt;attribute name="Host"gt;${jboss.bind.address}lt;/attributegt;
lt;attribute name="BindAddress"gt;${jboss.bind.address}lt;/attributegt;
lt;/mbeangt;

to:

lt;!-- Disabled to address CVE-2005-2006
lt;mbean code="org.jboss.web.WebService"
name="jboss:service=WebService"gt;
lt;attribute name="Port"gt;8083lt;/attributegt;
lt;attribute name="DownloadServerClasses"gt;truelt;/attributegt;
lt;attribute name="Host"gt;${jboss.bind.address}lt;/attributegt;
lt;attribute name="BindAddress"gt;${jboss.bind.address}lt;/attributegt;
lt;/mbeangt;
--gt;

This is tracked by the Mitre CVE ID CVE-2005-2006.

2) Pending Vulnerabilities, Solutions, and Work-Arounds

- zope

Zope honors file inclusion directives in RestructuredText objects
which potentially allowed attackers to execute arbitrary code (Zope
Hotfix 2005-10-09).

Updates are currently being QA tested.

All SUSE LINUX products gt;= 9.1 and SLES9 are affected.

- phpMyAdmin cross site scripting and file inclusion problems

We are preparing updates for the following issues:

- multiple cross-site scripting (XSS) bugs (CVE-2005-3301,
CVE-2005-2869, PMASA-2005-5).

- multiple file inclusion vulnerabilities that allowed an attacker
to include arbitrary files (CVE-2005-3300, CVE-2005-3301,
PMASA-2005-5).

All SUSE LINUX products are affected.

- libdga format string problem

libgda contains two format string bugs in logging routines. Those
bugs could potentially indirectly lead to arbitrary code execution
via applications that link against libgda and supply data to libgda
(CVE-2005-2958).

Updates are currently being QA tested.

All SUSE LINUX products and SLES9 are affected.

- php4,php5

Stefan Esser discovered a cross-site scripting bug in the phpinfo()
function (CVE-2005-3388), a bug that allows an attacker to enable
register_globals (CVE-2005-3389) and a bug that allows an attacker
to overwrite the $GLOBALS array (CVE-2005-3390).

We are preparing updates for these issues.

All SUSE LINUX based products are affected.

- gnump3d various problems
Steve Kemp discovered a cross-site scripting bug (CVE-2005-3122) and
a directory traversal bug (CVE-2005-3123) in gnump3d.

We are preparing updates for these issues.

All SUSE LINUX products are affected.

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 lt;filegt;

replacing lt;filegt; with the name of the file containing the announcement.
The output for a valid signature looks like:

gpg: Signature made lt;DATEgt; using RSA key ID 3D25D3D9
gpg: Good signature from "SuSE Security Team lt;security@suse.degt;"

where lt;DATEgt; 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 lt;file.rpmgt;

to verify the signature of the package, replacing lt;file.rpmgt; 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 included at the end of this
announcement.
