Updated OpenSSH packages are now available that fix bugs that may be remotely exploitable. [Updated 17 Sep 2003] Updated packages are now available to fix additional buffer manipulation problems which were fixed in OpenSSH 3.7.1. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0695 to these additional issues. We have also included fixes from Solar Designer for some additional memory bugs. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0682 to these issues.

The sendmail packages in Slackware 8.1, 9.0, and -current have been patched to fix security problems. These issues seem to be remotely exploitable, so all sites running sendmail should upgrade right away.

Upgraded OpenSSH 3.7.1p1 packages are available for Slackware 8.1, 9.0 and -current. These fix additional buffer management errors that were not corrected in the recent 3.7p1 release. The possibility exists that these errors could allow a remote exploit, so we recommend all sites running OpenSSH upgrade to the new OpenSSH package immediately.

A buffer management error was discovered in all versions of openssh prior to version 3.7. According to the OpenSSH team's advisory: "It is uncertain whether this error is potentially exploitable, however, we prefer to see bugs fixed proactively." There have also been reports of an exploit in the wild.

Several bugs have been found in OpenSSH's buffer handling. It is not known if these bugs are exploitable, but as a precaution an upgrade is advised.

This advisory is an addition to the earlier DSA-382-1 advisory: two more buffer handling problems have been found in addition to the one described in DSA-382-1. It is not known if these bugs are exploitable, but as a precaution an upgrade is advised.

A vulnerability was discovered in all versions of KDE 2.2.0 up to and including 3.1.3. KDM does not check for successful completion of the pam_setcred() call and in the case of error conditions in the installed PAM modules, KDM may grant local root access to any user with valid login credentials. It has been reported to the KDE team that a certain configuration of the MIT pam_krb5 module can result in a failing pam_setcred() call which leaves the session alive and would provide root access to any regular user. It is also possible that this vulnerability can likewise be exploited with other PAM modules in a similar manner.

Updated KDE packages that resolve a local security issue with KDM PAM support and weak session cookie generation are now available.

The openssh package is the most widely used implementation of the secure shell protocol family (ssh). It provides a set of network connectivity tools for remote (shell) login, designed to substitute the traditional BSD-style r-protocols (rsh, rlogin). openssh has various authentification mechanisms and many other features such as TCP connection and X11 display forwarding over the fully encrypted network connection as well as file transfer facilities.

Starting today, we are opening a design contest for Mozilla Links. You have a chance to let your creativity be known and shape the look of this newsletter. Take your your best shot at either the Mozilla Links logo or the Mozilla Links newsletter look. You have until October 15th, 2003 to send us your work. Winners will be announced in the following issue to be released on October 28th.

Upgraded OpenSSH packages are available for Slackware 8.1, 9.0 and - -current. These fix a buffer management error found in versions of OpenSSH earlier than 3.7. The possibility exists that this error could allow a remote exploit, so we recommend all sites running OpenSSH upgrade to the new OpenSSH package immediately.

A bug has been found in OpenSSH's buffer handling where a buffer could be marked as grown when the actual reallocation failed.

Updated OpenSSH packages are now available that fix a bug that may be remotely exploitable.

Today we feature a very interesting interview with Havoc Pennington. Havoc works for Red Hat, he is heading the desktop team, while he is well known also for his major contributions to GNOME, his GTK+ programming book, plus the freedesktop.org initiative which aims to standardize the X11 desktop environments. In the following interview we discuss about the changes inside Red Hat, Xouvert, freedesktop.org and Gnome's future, and how Linux, in general, is doing in the desktop market.

MySQL, a popular relational database system, contains a buffer overflow condition which could be exploited by a user who has permission to execute "ALTER TABLE" commands on the tables in the "mysql" database. If successfully exploited, this vulnerability could allow the attacker to execute arbitrary code with the privileges of the mysqld process (by default, user "mysql"). Since the "mysql" database is used for MySQL's internal record keeping, by default the mysql administrator "root" is the only user with permission to alter its tables.

Four vulnerabilities have been discovered in XFree86.

Several vulnerabilities were discovered by blexim(at)hush.com in the font libraries of XFree86 version 4.3.0 and earlier. These bugs could potentially lead to execution of arbitrary code or a DoS by a remote user in any way that calls these functions, which are related to the transfer and enumeration of fonts from font servers to clients.

Alexander Hvostov, Julien Blache and Aurelien Jarno discovered several security-related problems in the sane-backends package, which contains an API library for scanners including a scanning daemon (in the package libsane) that can be remotely exploited. Thes problems allow a remote attacker to cause a segfault fault and/or consume arbitrary amounts of memory. The attack is successful, even if the attacker's computer isn't listed in saned.conf.

The well known and widely used mail client pine is vulnerable to a buffer overflow. The vulnerability exists in the code processing 'message/external-body' type messages. It allows remote attackers to execute arbitrary commands as the user running pine. Additionally an integer overflow in the MIME header parsing code has been fixed.
