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.

- gpg2
GnuPG2 was vulnerable to arbitrary code execution by context-dependent
attackers because of reusing a freed pointer when verifying a signature
or by importing a certificate with many "Subject Alternate Names".
(CVE-2010-2547)
Affected Products: SLE10-SP3, SLE11, openSUSE 11.1, 11.2, 11.3

- krb5
This update fixes a denial-of-service vulnerability in kadmind. A remote
attacker could send a malformed GSS-API token that triggers a NULL pointer
dereference. (CVE-2010-1321: CVSS v2 Base Score: 6.8)
Affected Products: SUSE Moblin 2.1

- kvirc
This update of kvirc does not further allow remote client to send
arbitrary CTCP commands. (CVE-2010-2785)
Affected Products: openSUSE 11.1, 11.2, 11.3

- libpcsclite1/pcsc-lite
This update of pcsc-liste fixes two vulnerabilities:
- CVE-2009-4901: Local denial of service (daemon crash) via crafted
SCARD_SET_ATTRIB message data, a related issue to
CVE-2010-0407.
- CVE-2009-4902: A buffer overflow might allow local users to gain
privileges via crafted SCARD_CONTROL message data,
this vulnerability exists because of an incorrect
fix for CVE-2010-0407.
Affected Products: openSUSE 11.2, 11.3

- libpython2_6-1_0
This update of python has a copy of libxmlrpc that is vulnerable to
denial of service bugs that can occur while processing malformed XML input.
- CVE-2009-2625: CVSS v2 Base Score: 5.0: Permissions, Privileges,
and Access Control (CWE-264)
- CVE-2009-3720: CVSS v2 Base Score: 5.0: denial of service
- CVE-2009-3560: CVSS v2 Base Score: 5.0): Buffer Errors (CWE-119)
Affected products: SUSE Moblin 2.0

- libvorbis
This update of libvorbis fixes a memory corruption while parsing OGG files.
The bug was exploitable by remote attackers to cause an application crash
and could probably be exploited to execute arbitrary code.
(CVE-2009-2663: CVSS v2 Base Score: 6.8)
Affected products: SUSE Moblin 2.0 and 2.1

- libwebkit
The libwebkit browser engine version 1.2.3 fixes several security relevant
bugs:
(CVE-2010-1386, CVE-2010-1392, CVE-2010-1405, CVE-2010-1407,
CVE-2010-1416, CVE-2010-1417, CVE-2010-1665, CVE-2010-1418,
CVE-2010-1421, CVE-2010-1422, CVE-2010-1501, CVE-2010-1767,
CVE-2010-1664, CVE-2010-1758, CVE-2010-1759, CVE-2010-1760,
CVE-2010-1761, CVE-2010-1762, CVE-2010-1770, CVE-2010-1771,
CVE-2010-1772, CVE-2010-1773, CVE-2010-1774)
Affected Products: openSUSE 11.3

- squidGuard
Two buffer overflows in squidGard were fixed:
- CVE-2009-3700: Buffer overflow in sgLog.c in squidGuard 1.3 and 1.4
allows remote attackers to cause a denial of service
(application hang or loss of blocking functionality)
via a long URL with many / (slash) characters, related
to "emergency mode."
- CVE-2009-3826: Multiple buffer overflows in squidGuard 1.4 allow remote
attackers to bypass intended URL blocking via a long URL,
related to (1) the relationship between a certain buffer
size in squidGuard and a certain buffer size in Squid
and (2) a redirect URL that contains information about
the originally requested URL.
Affected Products: openSUSE 11.1, 11.2, 11.3

- strongswan
Remote unauthenticated attackers could cause a buffer overflow in
strongswan's IKE deamon by using specially crafted certificates or
identify information. Attackers could potentially exploit that to execute
code (CVE-2010-2628).
Affected Products: openSUSE 11.2, 11.3, SLE11-SP1

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

replacing with the name of the file containing the announcement.
The output for a valid signature looks like:

gpg: Signature made using RSA key ID 3D25D3D9
gpg: Good signature from "SuSE Security Team "

where 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
