Rob Holland discovered several programming errors in WordNet, an electronic lexical database of the English language. These flaws could allow arbitrary code execution when used with untrusted input, for example when WordNet is in use as a back end for a web application.

It has been discovered that Slash, the Slashdot Like Automated Storytelling Homepage suffers from two vulnerabilities related to insufficient input sanitation, leading to execution of SQL commands (CVE-2008-2231) and cross-site scripting (CVE-2008-2553).

This vulnerability affects only smart cards and USB crypto tokens based on Siemens CardOS M4, and within that group only those that were initialised with OpenSC. Users of other smart cards and USB crypto tokens, or cards that have been initialised with some software other than OpenSC, are not affected.

In DSA-1597-1, an update was announced for multiple vulnerabilities in the mt-daapd audio server. One of the fixes introduced a regression preventing successful authentication to the administration interface. An updated release is available which corrects this problem. For reference, the original advisory text follows.

A cross-site request forgery vulnerability was discovered in Django that, if exploited, could be used to perform unrequested deletion or modification of data. Updated versions of Django will now discard posts from users whose sessions have expired, so data will need to be re-entered in these cases.

Drew Yaro of the Apple Product Security Team reported multiple uses of uninitialized values in libtiff's LZW compression algorithm decoder. An attacker could create a carefully crafted LZW-encoded TIFF file that would cause an application linked to libtiff to crash or potentially execute arbitrary code (CVE-2008-2327). The updated packages have been patched to prevent this issue.

Chaskiel M Grundman found that OpenSC would initialize smart cards with the Siemens CardOS M4 card operating system without proper access rights. This allowed everyone to change the card's PIN without first having the PIN or PUK, or the superuser's PIN or PUK (CVE-2008-2235).

Rob Holland found several programming errors in WordNet which could lead to the execution or arbitrary code when used with untrusted input (CVE-2008-2149).

Two denial of service vulnerabilities were discovered in the ipsec-tools racoon daemon, which could allow a remote attacker to cause it to consume all available memory (CVE-2008-3651, CVE-2008-3652). The updated packages have been patched to prevent these issues.

Updated libtiff packages that fix a security issue and a bug are now available for Red Hat Enterprise Linux 5. Multiple uses of uninitialized values were discovered in libtiff's Lempel-Ziv-Welch (LZW) compression algorithm decoder. An attacker could create a carefully crafted LZW-encoded TIFF file that would cause an application linked with libtiff to crash or, possibly, execute arbitrary This update has been rated as having important security impact by the Red Hat Security Response Team.

Updated libtiff packages that fix various security issues and a bug are now available for Red Hat Enterprise Linux 4. A buffer overflow flaw was discovered in the tiff2pdf conversion program distributed with libtiff. An attacker could create a TIFF file containing UTF-8 characters that would, when converted to PDF format, cause tiff2pdf to crash, or, possibly, execute arbitrary code. This update has been rated as having important security impact by the Red Hat Security Response Team.

Updated libtiff packages that fix a security issue are now available for Red Hat Enterprise Linux 2.1 and 3.Multiple uses of uninitialized values were discovered in libtiff's Lempel-Ziv-Welch (LZW) compression algorithm decoder. An attacker could create a carefully crafted LZW-encoded TIFF file that would cause an application linked with libtiff to crash or, possibly, execute arbitrary code. This update has been rated as having important security impact by the Red Hat Security Response Team.

New php packages are available for Slackware 10.2 and 11.0 to fix security issues. These releases are the last to contain PHP 4.4.x, which was upgraded to version 4.4.9 to fix PCRE issues and other bugs. Please note that this is the FINAL release of PHP4, and it has already passed the announced end-of-life. Sites should seriously consider migrating to PHP5 rather than upgrading to php-4.4.9.

New Amarok packages are available for Slackware 11.0, 12.0, 12.1, and -current to fix security issues. In addition, new supporting libgpod packages are available for Slackware 11.0 and 12.0, since a newer version of libgpod than shipped with these releases is required to run Amarok version 1.4.10. The Magnatune music library plugin made insecure use of the /tmp directory, allowing malicious local users to overwrite files owned by the user running Amarok through symlink attacks.

Andreas Solberg discovered that libxml2 did not handle recursive entities safely. If an application linked against libxml2 were made to process a specially crafted XML document, a remote attacker could exhaust the system's CPU resources, leading to a denial of service.

Drew Yao discovered that the TIFF library did not correctly validate LZW compressed TIFF images. If a user or automated system were tricked into processing a malicious image, a remote attacker could execute arbitrary code or cause an application linked against libtiff to crash, leading to a denial of service.
