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.
- Acroread wrapper script minor /tmp race
Adobe Acrobat Reader 8.1.2 contained a /tmp race in its "acroread" wrapper script in the SSL certificate handling. (CVE-2008-0883) This problem is not triggered by just starting acrobat reader, but only on certificate handling.
Furthermore Acrobat Reader contained several duplicated copies of system libraries, which have been removed by this update to make sure they are up-to-date security wise by using the system provided ones.
Also on x86-64 platforms, the Mozilla embedding detection did not work and was fixed, so the Splashscreen and Help are again displayed.
Updates have been released on SUSE Linux Enterprise Desktop 10, SUSE Linux 10.1, openSUSE 10.2 and 10.3.
Updates for version 7 for Novell Linux Desktop 9 and SUSE Linux Enterprise Server 9 are still pending.
- Asterisk security issues
A security update was released for the PBX Asterisk, fixing following security issues:
CVE-2007-6430: Attackers could bypass host based authentication by using a valid user name.
CVE-2007-6170: Attackers could inject SQL commands under certain circumstances if 'cdr_pgsql' was used.
Asterisk was updated on SUSE Linux 10.1 and openSUSE 10.2.
- cacti various vulnerabilities
The following vulnerabilities were fixed in cacti: - CVE-2008-0783: multiple XSS vulnerabilities - CVE-2008-0784: path disclosure - CVE-2008-0785: multiple SQL injections - CVE-2008-0786: HTTP response splitting on very old PHP instances
Cacti is included in SUSE Linux 10.1, openSUSE 10.2 and 10.3 and was fixed there.
- compat-openssl097g security fixes
This update of compat-openssl097g fixes a off-by-one buffer overflow in function SSL_get_shared_ciphers(). This vulnerability potentially allows remote code execution; depending on memory layout of the process. (CVE-2007-5135)
We released updates for openssl already, but an update for the compat 0.9.7g openssl libraries was missing and is provided with this patch.
Released for SUSE Linux Enterprise 10, SUSE Linux 10.1 and openSUSE 10.2, 10.3.
- icu regular expression problems
Certain regular expressions could crash the ICU library (CVE-2007-4770, CVE-2007-4771).
Updated icu packages have been released for all distributions.
- libcdio buffer overflow
A security bug was fixed in libcdio. Long file names in ISO file systems with Joliet extension could cause a buffer overflow in libcdio (CVE-2007-6613).
libcdio fixes were released for all SUSE Linux products.
- wireshark/ethereal security problems
The network analyzer wireshark (formerly known as ethereal) was updated to fix the following security bugs:
- CVE-2008-1070: The SCTP dissector could crash on reception of bad packets - CVE-2008-1071: The SNMP dissector could crash on reception of bad packets - CVE-2008-1072: The TFTP dissector could crash Wireshark (maybe a bug in the Cairo library on specific platforms)
- Jakarta Tomcat security problems
Various security issues in Jakarta Tomcat have been fixed:
- CVE-2006-7196: Cross-site scripting (XSS) vulnerability in example JSP applications - CVE-2007-3382: Handling of cookies containing a ' character - CVE-2007-3385: Handling of " in cookies - CVE-2007-5461: tomcat path traversal / information leak - CVE-2007-1860: directory traversal - CVE-2008-0128: tomcat https information disclosure - CVE-2005-2090: tomcat HTTP Request Smuggling
Updates have been released for all distributions.
- perl-Tk GIF security problem
Specially crafted GIF files could crash perl-Tk (CVE-2006-4484).
Fixed packages have been released for all distributions. ______________________________________________________________________________

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 email@example.com"
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 firstname.lastname@example.org 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:
email@example.com - General Linux and SUSE security discussion. All SUSE security announcements are sent to this list. To subscribe, send an e-mail to firstname.lastname@example.org.
email@example.com - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list. To subscribe, send an e-mail to firstname.lastname@example.org.
