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.

- ipsec-tools remote denial of service

A bug in the IKE daemon "racoon" allowed remote attackers to shut
down established tunnels (CVE-2007-1841).

This problem was fixed for all SUSE Linux based distributions.


- inkscape format string problems

Several format string problems where fixed in inkscape.

CVE-2007-1463: A format string vulnerability in Inkscape allows
user-assisted remote attackers to execute arbitrary code via
format string specifiers in a URI, which is not properly handled
by certain dialogs.

CVE-2007-1464: Format string vulnerability in the whiteboard
Jabber protocol in Inkscape allows user-assisted remote attackers
to execute arbitrary code via unspecified vectors.

All products containing inkscape were fixed.


- rarpd minor denial of service

A minor denial of service problem was fixed in rarpd, which was
sending reply packets with increasing size leading to rarpd not
being able to send packets at all anymore and so disabling itself.

This bug has been fixed for all distributions containing rarpd.


- ImageMagick/GraphicsMagick integer overflows

ImageMagick and GraphicsMagick were updated to fix integer overflows
in the DCM and XWD code. These bugs could be exploited remotely
via other applications.

The problems are tracked by the Mitre CVE IDs CVE-2007-1667 and
CVE-2007-1797 and were fixed for all distributions.


- mod_perl denial of service

The mod_perl Apache1 module was affected by insufficient quoting
of special characters in the PATH_INFO variable which could lead
to excessive resource consumption and a denial of service via a
specially crafted URL.

This issue is tracked by the Mitre CVE ID CVE-2007-1349 and was
fixed for SUSE Linux Enterprise Server 8 and 9 and dependent
products. Newer Enterprise Server versions or SUSE Linux products
are not affected, since they only contain the apache2 perl module,
which is not affected by the problem.


- dovecot path traversal

A bug in dovecot allowed users to read compressed mailboxes of
other users under certain circumstances.

This problem is tracked by the Mitre CVE ID CVE-2007-2231 and
was fixed for SUSE Linux 10.1 and openSUSE 10.2. Other products
do not contain the dovecot package.

2) Pending Vulnerabilities, Solutions, and Work-Arounds

- Month of PHP bugs
We are currently working on fixing all the bugs found by the Month
of PHP bugs project and will release updates when ready.

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.

- 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.
