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.
- cyrus-imapd
This update fixes another buffer overflow in the Sieve code. This can
be exploited by users allowed to use their own sieve scripts to execute
arbitrary code remotely.
CVE-2009-3235: CVSS v2 Base Score: 7.5 (HIGH) (AV:N/AC:L/Au:N/C:P/I:P/A:P)
Additionally the handling of long headers was improved.
Affected products: openSUSE 10.3-11.1, SLES9, SLE10, SLE11
- neon/libneon
neon did not properly handle embedded NUL characters in X.509
certificates when comparing host names. Attackers could exploit that
to spoof SSL servers.
CVE-2009-2408: CVSS v2 Base Score: 7.5 (HIGH) (AV:N/AC:L/Au:N/C:P/I:P/A:P)
Specially crafted XML documents that contain a large number of
nested entity references could cause neon to consume large amounts
of CPU and memory (CVE-2009-2473).
CVE-2009-2473: CVSS v2 Base Score: 4.3 (MEDIUM) (AV:N/AC:M/Au:N/C:N/I:N/A:P)
Affected products: openSUSE 10.3-11.1, SLES9, SLE10, SLE11
- freeradius
This update of freeradius fixes a remote denial-of-service bug in function
rad_decode() which can be triggered by zero-length Tunnel-Password attri-
butes to make radiusd crash.
CVE-2009-3111: CVSS v2 Base Score: 5.0 (MEDIUM) (AV:N/AC:L/Au:N/C:N/I:N/A:P)
Affected products: SLE10 SP3
- strongswan
The previous fix for a flaw in the ASN.1 parser was incomplete and
had to be reworked.
This could lead to crashes of the pluto IKE daemon.
CVE-2009-2661: CVSS v2 Base Score: 5.0 (MEDIUM) (AV:N/AC:L/Au:N/C:N/I:N/A:P)
Affected products: SLE10 SP3
- openldap2
This update of openldap2 makes SSL certificate verification more robust
against uses of the special character \0 in the subjects name.
CVE-2009-2408: CVSS v2 Base Score: 7.5 (HIGH) (AV:N/AC:L/Au:N/C:P/I:P/A:P)
Affected products: SLE10 SP3
- apache2-mod_jk
Certain HTTP request could confuse the JK connector in Apache Tomcat which
could result in a user seeing responses destined for other users.
CVE-2008-5519: CVSS v2 Base Score: 2.6 (LOW) (AV:N/AC:H/Au:N/C:P/I:N/A:N)
Affected products: openSUSE 10.3-11.1
- expat
Specially crafted XML documents could make expat run into an enless loop,i
therefore locking up applications using expat.
CVE-2009-3720: CVSS v2 Base Score: 5.0 (MEDIUM) (AV:N/AC:L/Au:N/C:N/I:N/A:P)
Affected products: openSUSE 10.3-11.1, SLES9, SLE10, SLE11
- xpdf
Specially crafted PDF files could cause buffer overflows in xpdf
when viewing such a document.
CVE-2009-3603: CVSS v2 Base Score: 9.3 (HIGH) (AV:N/AC:M/Au:N/C:C/I:C/A:C)
CVE-2009-3604: CVSS v2 Base Score: 9.3 (HIGH) (AV:N/AC:M/Au:N/C:C/I:C/A:C)
CVE-2009-3605: CVSS v2 Base Score: 10.0 (HIGH) (AV:N/AC:L/Au:N/C:C/I:C/A:C)
CVE-2009-3606: CVSS v2 Base Score: 9.3 (HIGH) (AV:N/AC:M/Au:N/C:C/I:C/A:C)
CVE-2009-3608: CVSS v2 Base Score: 9.3 (HIGH) (AV:N/AC:M/Au:N/C:C/I:C/A:C)
CVE-2009-3609: CVSS v2 Base Score: 4.3 (MEDIUM) (AV:N/AC:M/Au:N/C:N/I:N/A:P)
Affected products: openSUSE 10.3-11.1, SLES9, SLE10, SLE11
- mozilla-nspr
This update fixes a bug in the Mozilla NSPR helper libraries, which could
be used by remote attackers to potentially execute code via javascript
vectors.
MFSA 2009-59:
Security researcher Alin Rad Pop of Secunia Research reported a heap-based
buffer overflow in Mozilla's string to floating point number conversion
routines. Using this vulnerability an attacker could craft some malicious
JavaScript code containing a very long string to be converted to a floating
point number which would result in improper memory allocation and the execution
of an arbitrary memory location. This vulnerability could thus be leveraged by
the attacker to run arbitrary code on a victim's computer.
CVE-2009-1563: CVSS v2 Base Score: 10.0 (HIGH) (AV:N/AC:L/Au:N/C:C/I:C/A:C)
Affected products: openSUSE 11.0-11.1, SLE10, SLE11

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(a)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(a)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(a)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(a)opensuse.org>.
opensuse-security-announce(a)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(a)opensuse.org>.
=====================================================================
SUSE's security contact is <security(a)suse.com> or <security(a)suse.de>.
