Problem Description From CERT CA-2003-12: There is a vulnerability in sendmail that can be exploited to cause a denial-of-service condition and could allow a remote attacker to execute arbitrary code with the privileges of the sendmail daemon, typically root. 2. Vulnerable Supported Versions System Package ---------------------------------------------------------------------- OpenLinux 3.1.1 Server prior to sendmail-8.11.6-14.i386.rpm prior to sendmail-cf-8.11.6-14.i386.rpm prior to sendmail-doc-8.11.6-14.i386.rpm OpenLinux 3.1.1 Workstation prior to sendmail-8.11.6-14.i386.rpm prior to sendmail-cf-8.11.6-14.i386.rpm prior to sendmail-doc-8.11.6-14.i386.rpm OpenLinux 3.1 Server prior to sendmail-8.11.6-14.i386.rpm prior to sendmail-cf-8.11.6-14.i386.rpm prior to sendmail-doc-8.11.6-14.i386.rpm OpenLinux 3.1 Workstation prior to sendmail-8.11.6-14.i386.rpm prior to sendmail-cf-8.11.6-14.i386.rpm prior to sendmail-doc-8.11.6-14.i386.rpm 3. Solution The proper solution is to install the latest packages. Many customers find it easier to use the Caldera System Updater, called cupdate (or kcupdate under the KDE environment), to update these packages rather than downloading and installing them by hand. 4.
