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 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.
- imlib2
A security problem was fixed in imlib2 where loading a specific XPM
file could corrupt memory. (CVE-2008-5187)
Affected products: SLED 10 SP2, SLE SDK 10 (updates for other products
were already released)
- valgrind
valgrind reads a file .valgrindrc in the current directory.
Therefore local users could place such a file a world writable
directory such as /tmp and influence other users' valgrind when it's
executed there (CVE-2008-4865).
Affected products: SLES9/SDK (updates for other products were already
released)
- kvm
Rogue VNC clients could make the built in VNC server of kvm run into
an infinite loop (CVE-2008-2382)
An off-by-one bug limited the length of VNC passwords to seven
instead of eight (CVE-2008-5714)
Virtualized guests could potentially execute code on the host by
triggering a buffer overflow in the network emulation code via large
ethernet frames (CVE-2007-5729)
Virtualized guests could potentially execute code on the host by
triggering a heap based buffer overflow in the Cirrus Graphics card
emulation (CVE-2007-1320).
Affected products: openSUSE 11.0, 11.1
- cups
Previous updates for the PNG and HPGL filters were incomplete and
are corrected now (CVE-2008-3641, CVE-2008-5286).
Affected products: openSUSE 10.3, 11.0, SLE10-SP2, SLES9
- lynx
This update of lynx fixes two security bugs:
- untrusted search path allows execution of arbitrary commands via
.mailcap or mime.types file (CVE-2006-7234)
- when advanced mode is enabled and lynx is used as URL handler, remote
attackers can execute arbitrary commands (CVE-2008-4690)
Affected products: NLD 9 SDK, SLE SDK 10 SP2, SLES SDK 9 (updates for
other products were already released)
- xterm
XTerm evaluated various ANSI Escape sequences so that command execution
was possible if an attacker could pipe raw data to an xterm.
(CVE-2008-2383)
(It is usually not recommended to display raw data on an xterm.)
Affected products: openSUSE 10.3-11.0, SLE10-SP2, (SLES9 packages will
be released within this week)

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>.
