______________________________________________________________________________

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.

- resmgr security problems
The resmgr package was updated to fix following problems:

- resmgrd granted access to all usb devices if access to one one usb
device was granted via "usb:lt;busgt;,lt;devgt;" notation.

- Class specific exclude rules did not match devices that set their
class ID at interface level.

This update also fixes the following non-security bugs:

- a file descriptor leak

- resmgrd often logged unnecessary ACL error messages

- the init script cleared /var/run/resmgr/classes even if resmgrd
was already running

- php4,php5 security problems
PHP4 and PHP5 were updated to fix the following security issues:

- Cross-Site-Scripting (XSS) bugs (CVE-2006-0208), affecting both
php4 and php5.

- A problem with HTTP response splitting (CVE-2006-0207) using Set-Cookie
headers allowed attackers to inject arbitrary HTTP headers.

This update also fixes the following non-security issues:

- crash when including more than one php script via SSI
- the php5 binary is now compiled in "cli" mode instead of "gui" mode.

This affects all SUSE Linux based products containing php4 or php5.

- ethereal security problems

This update of Ethereal fixes a stack-based buffer overflow in
the dissect_ospf_v3_address_prefix function of the OSPF protocol
dissector. This bug can be exploited remotely by sending crafted
packets to execute arbitrary code (CVE-2005-3651).

Additionally a bug in the GTP dissector was fixed to avoid a remote
denial-of-service attack (CVE-2005-4585).

All SUSE Linux based products are affected.

This patch was released on Feb 6th.

- apache2 cross site scripting in imagemap and mod_ssl DoS

This update fixes the following security problems in the Apache2
web server modules:

- a cross-site-scripting bug in the imagemap module mod_imap
(CVE-2005-3352)

- a bug in mod_ssl that allowed attackers to crash apache
(CVE-2005-3357)

This affects all SUSE Linux based products.
This patch was released on Feb 7th.

2) Pending Vulnerabilities, Solutions, and Work-Arounds

- Kernel security issues

Various kernel security issues are known, for which we have prepared
security updates.

All the kernel patches have been released on Thursday, except the
SLES 8 and SLES 9 kernels for the s390 and s390x (zSeries) platforms.

When the latter ones have been released, a separate full security
advisory will be published.

- gpg and liby2util affected on more distributions

While we have a released a security advisory for GPG signature
problems in gpg and in liby2util for SUSE Linux 9.3 and 10.0 we
have now found that other versions are affected too.

We are preparing updates for the other affected versions and will
release a separate advisory at this time.

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.
