Content of this advisory:
1) Solved Security Vulnerabilities:
- postgresql denial of service and potential privilege escalation
- pptpd remote denial of service
- freeradius remote denial of service
- xfsdump information disclosure
2) Pending Vulnerabilities, Solutions, and Work-Arounds:

3) Authenticity Verification and Additional Information
______________________________________________________________________________
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.
- postgresql denial of service and potential privilege escalation
This update fixes two vulnerabilities that affect the backend
server and can only be exploited by authenticated users to cause
a denial-of-service, or maybe to access other tables/databases
without authentication.
These issues are tracked by the Mitre CVE IDs CVE-2007-0555 and
CVE-2007-0556 and were fixed for all affected products.
- pptpd remote denial of service
Specially crafted GRE packets can crash the point to point daemon
pptpd.
This issue is tracked by the Mitre CVE ID CVE-2007-0244 and affected
only openSUSE 10.2.
- freeradius remote denial of service
A memory leak in the code for handling EAP-TTLS tunnels of FreeRADIUS
could be exploited by attackers to crash freeradius.
This issue is tracked by the Mitre CVE ID CVE-2007-2028 and was
fixed for all products.
- xfsdump information disclosure
The program xfs_fsr created a temporary directory with unrestricted
read and write permissions, allowing information disclosure or file
overwrite when xfs filesystems are used.

2) Pending Vulnerabilities, Solutions, and Work-Arounds
- Month of PHP bugs / PHP 5.2.2
We are currently preparing updates for the bugs found by the Month
of PHP bugs project and fixed in PHP 5.2.2 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 <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 "
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
to verify the signature of the package, replacing 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.
To subscribe, send an e-mail to
.
suse-security-announce@suse.com
- SUSE's announce-only mailing list.
Only SUSE's security announcements are sent to this list.
