______________________________________________________________________________
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 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.
- rsync heap overflow in xattr code
A remotely exploitable heap overflow in rsync's xattr code has
been fixed. CVE-2008-1720 has been assigned to this issue.
rsync was fixed on openSUSE 10.3.
- MozillaFirefox 2.0.0.14 security release
Mozilla Firefox was brought to security update version 2.0.0.14.
Following security problems were fixed:
- MFSA 2008-20/CVE-2008-1380: Fixes for security problems in the
JavaScript engine described in MFSA 2008-15 (CVE-2008-1237) introduced
a stability problem, where some users experienced frequent crashes
during JavaScript garbage collection. These crashes may be exploitable
if someone finds a reliable way to trigger the crash.
We were not able to reproduce the crashes internally. Updates have been
released on SLE 10, SUSE Linux 10.1, openSUSE 10.2 and 10.3.
- poppler PDF problems
Specially crafted PDF files with embedded fonts could potentially be
abused to trick applications that process PDF files into executing
arbitrary code (CVE-2008-1693).
Fixes for poppler for all distributions containing poppler have
been released.
- nagios cross site scripting problems
Several cross site scripting (XSS) issues in nagios were fixed
(CVE-2007-5624, CVE-2007-5803, CVE-2008-1360).
SLE 10, openSUSE 10.2 and 10.3 received fixed nagios packages.
- lighttpd SSL denial of service
The web server lighttpd had a problem, where an error in one
SSL connection could lead to termination of all SSL connections
(CVE-2008-1531)
This problem has been fixed in SLE 10, SUSE Linux 10.1, openSUSE
10.2 and 10.3.
- sarg various buffer overflows
Multiple stack buffer overflows have been fixed in the Squid logfile
analyzer sarg. (CVE-2008-1922)
sarg updates have been released for SUSE Linux 10.1, openSUSE 10.2
and 10.3.
- squid denial of service fix
A flaw in a previous security update could cause squid to crash
under certain circumstances (CVE-2008-1612).
squid was updated on all distributions.
- bzip2 decoder denial of service
Specially crafted files could crash the bzip2-decoder
(CVE-2008-1372).
bzip2 was updated on all distributions.
- kdelibs3 unix signal handling
Start_kdeinit did not handle unix signals the right way
(CVE-2008-1671)
This was only a problem in openSUSE 10.3 and fixed there.
- texlive-bin dvips overflows
Buffer overflows in dvips and dviljk could be triggered by specially
crafted dvi files (CVE-2007-5935, CVE-2007-5937). dvips additionally
created temporary files in an insecure manner (CVE-2007-5936).
Only openSUSE 10.3 updates were missing for this issue, the others
were released several weeks ago already.
- kdelibs4 heap overflow in PNG loader of KHTML
A heap overflow in the PNG loader of KHTML has been
fixed. CVE-2008-1670 has been assigned to this issue.
Only openSUSE 10.3 was affected and fixed.
- Sun Java 1.6.0 u6 security update
Sun Java was updated to 1.6.0u6 to fix several bugs and potentially
also security problems.
Sun has however not published any details regarding Security
Vulnerabilities in this update.
Only openSUSE 10.3 contains Sun Java 1.6.0 and was fixed.

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.
