Content of this advisory:
1) Solved Security Vulnerabilities:
- orarun insecure group membership
- xpdf code base buffer overflow
- findutils-locate: core clean cron-job any file removal problem
- tcpdump BGP packet handler overflow
2) Pending Vulnerabilities, Solutions, and Work-Arounds:
- next kernel update
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.

- orarun insecure group membership

SUSE provides a "orarun" package that helps with setting up Oracle
servers.

This package creates on installation a "oracle" user. Up to now
the
user is in the group "disk" to allow setting up raw disk
partitions.

This however allows the oracle user later to escalate privileges
if for instance a program or script in the Oracle suite running as
"oracle" user is compromised.

We recommend removing the "disk" group membership from the
"oracle"
user.

You can do so by doing:
usermod -g oinstall -G dba oracle

We will not provide fixed packages at this time since these could
break customer setups, but future service packs or products will
leave out the disk group.

We thank José M. Fandiño for reporting this problem.


- xpdf code base buffer overflow

A buffer overflow in the xpdf code contained in cups,poppler,kpdf
and others could be exploited by attackers to potentially execute
arbitrary code (CVE-2007-3387).

Only XPDF 3 code derivatives were affected, XPDF 2 code deviates do
not write into the memory.


- findutils-locate: core clean cron job any file removal problem

The cron job that deletes old core files could be tricked to delete
arbitrary files. Old core files are deleted if DELETE_OLD_CORE=yes
is set. That is not the case by default though.

The findutils-locate package was updated to fix this issue on the
affected products.

SUSE Linux Enterprise Server 9, 10, and SUSE Linux 10.0 and 10.1
were affected.

We thank Jan Minář for reporting this problem.


- tcpdump BGP packet handler overflow

tcpdump was updated to fix a buffer overflow that could be triggered
when displaying BGP packets (CVE-2007-3798).

All SUSE Linux based products were affected.

2) Pending Vulnerabilities, Solutions, and Work-Arounds

- next kernel update

A SLE 10 kernel update will be released in the next weeks to catch
up on post-Service Pack 1 fixes and current security fixes.

A SUSE Linux 10.1 kernel update will be released with the same
code base.

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@suse.de>"

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@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
<opensuse-security+subscribe@opensuse.org>.

opensuse-security-announce@opensuse.org
- SUSE's announce-only mailing list.
Only SUSE's security announcements are sent to this list.
To subscribe, send an e-mail to
<opensuse-security-announce+subscribe@opensuse.org>.
