______________________________________________________________________________

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.

- PHP security problems

Multiple security bugs were fixed in PHP:

- Predictable generation of an initialization vector (IV) in the
mcrypt extension (CVE-2007-2727)

- Additional cookie attributes could be injected via a session id
(CVE-2007-3799)

- Specially crafted files could cause integer overflows in gd and
leverage them to at least crash gd based applications
(CVE-2007-3472, CVE-2007-3475, CVE-2007-3476, CVE-2007-3477,
CVE-2007-3478)

These GD fixes apply to a copy of the GD library in the PHP sources.

- Insufficient validation of parameters in the substr_count function
(CVE-2007-2748).

- Predictable generating of an initialization vector (IV) in the
soap extension (CVE-2007-2728)

PHP4 and PHP5 packages were updated for all SUSE Linux distributions.


- moodle remote file inclusion

Moodle was updated to 1.7.2 to fix several problems, including a
remote file inclusion (CVE-2007-1429).

Moodle is only on openSUSE 10.2 and was fixed there.


- Tomcat5 directory traversal

Tomcat5 was updated to fix a problem, where certain characters of
the URL were not properly filtered. This allowed directory reverse
traversal attacks to access the web-root of tomcat. (CVE-2007-0450)

This affected all our distributions containing tomcat5.


- lighttpd various security problems

Multiple bugs in lighttpd allowed remote attackers to crash lighttpd,
circumvent access restrictions or even execute code.

These issues are tracked by the Mitre CVE ids:
CVE-2007-3946, CVE-2007-3947, CVE-2007-3948, CVE-2007-3949,
CVE-2007-3950

and have been fixed for SUSE Linux Enterprise 10, SUSE Linux 10.1
and openSUSE 10.2.


- Asterisk various security problems

The Open Source PBS Asterisk was updated to fix multiple bugs
that allowed remote attackers to crash the asterisk server or even
execute arbitrary code depending on configuration (CVE-2007-3762,
CVE-2007-3763, CVE-2007-3764).

Asterisk was fixed for SUSE Linux 10.0, SUSE Linux 10.1 and
openSUSE 10.2.


- libarchive security problems

Several problems in libarchive were fixed.

Specially crafted tar-archives could cause programs based on
libarchive to crash, to run into an endless loop or potentially
to even execute arbitrary code (CVE-2007-3641, CVE-2007-3644,
CVE-2007-3645).


- xpdf buffer overflow

A buffer overflow in xpdf could be exploited by attackers to
potentially execute arbitrary code (CVE-2007-3387).

Various other tools contain copies of the xpdf code and are also
being updated. (poppler, libextractor, kdegraphics3-pdf, etc.)

We have released some of those packages (xpdf, kdegraphics3-pdf)
already and will release the others soon.

- evolution format string problem in memo viewer

Format string problems in the Memo Viewer of evolution could
be used to potentially execute code when viewing shared memos.
(CVE-2007-1002)

Affected are evolution of SLE 10, SUSE Linux 10.1 and openSUSE 10.2.
For SLE10 the fix was released with Service Pack 1 already, the
others have received their update now.

- kvirc command execution

A bug in the IRC-URI parser allowed attackers to execute arbitrary
commands by tricking a user into opening a specially crafted URI
in kvirc (CVE-2007-2951).

Updated packages have been released for SUSE Linux 10.0 - 10.2.

- wireshark / ethereal security problems

Various security problems were fixed in the wireshark 0.99.6 release,
which were back-ported to wireshark / ethereal:

CVE-2007-3389: Wireshark allowed remote attackers to cause a
denial of service (crash) via a crafted chunked encoding in an HTTP
response, possibly related to a zero-length payload.

CVE-2007-3390: Wireshark when running on certain systems, allowed
remote attackers to cause a denial of service (crash) via crafted
iSeries capture files that trigger a SIGTRAP.

CVE-2007-3391: Wireshark allowed remote attackers to cause a denial
of service (memory consumption) via a malformed DCP ETSI packet
that triggers an infinite loop.

CVE-2007-3392: Wireshark allowed remote attackers to cause a denial
of service via malformed (1) SSL or (2) MMS packets that trigger
an infinite loop.

CVE-2007-3393: Off-by-one error in the DHCP/BOOTP dissector in
Wireshark allowed remote attackers to cause a denial of service
(crash) via crafted DHCP-over-DOCSIS packets.


- gd various integer overflows

This update fixes multiple integer overflows in the gd library.
Specially crafted files could leverage them to at least crash gd
based applications (CVE-2007-3472, CVE-2007-3475, CVE-2007-3476,
CVE-2007-3477, CVE-2007-3478).

GD was updated for all SUSE Linux products, the update was released
on July 24th.


- Opera 9.22 release

Opera was updated to version 9.22 on July 24 to fix numerous defects
including some security problems. (CVE-2007-3929, CVE-2007-3819,
CVE-2007-3142)


- Clamav 0.91.1 release

This clamav version update to 0.91.1 fixes among other things the
long startup time of version 0.90.3 as well as a possibility to
crash clamav with specially crafted rar archives (CVE-2007-3725).

clamav was updated for all SUSE Linux based products that contain
clamav.

- gimp integer overflow in PSD handling

The image editor GIMP was updated to fix a integer overflow in the
handling of PSD files. By providing a crafted PSD file and tricking
the user to open it an attacker could execute code. (CVE-2007-2949)

GIMP was updated for all affected SUSE Linux products.
______________________________________________________________________________

2) Pending Vulnerabilities, Solutions, and Work-Arounds

- Mozilla Firefox 2.0.0.6

We will likely skip the Firefox 2.0.0.6 update and roll the fixes
into the 2.0.0.7 release in some weeks, since most problems fixed
are Windows only.

- Kernel Update

We are currently preparing a kernel update for SUSE Linux Enterprise
10 and SUSE Linux 10.1. A release date is not yet set.
______________________________________________________________________________

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.
To subscribe, send an e-mail to
<opensuse-security-announce+subscribe@opensuse.org>.
