Problem Description From CA-2003-07: Researchers at Internet Security Systems (ISS) have discovered a remotely exploitable vulnerability in sendmail. This vulnerability could allow an intruder to gain control of a vulnerable sendmail server. 2. Vulnerable Supported Versions System Package ---------------------------------------------------------------------- OpenLinux 3.1.1 Server prior to sendmail-8.11.6-13.i386.rpm prior to sendmail-cf-8.11.6-13.i386.rpm prior to sendmail-doc-8.11.6-13.i386.rpm OpenLinux 3.1.1 Workstation prior to sendmail-8.11.6-13.i386.rpm prior to sendmail-cf-8.11.6-13.i386.rpm prior to sendmail-doc-8.11.6-13.i386.rpm OpenLinux 3.1 Server prior to sendmail-8.11.6-13.i386.rpm prior to sendmail-cf-8.11.6-13.i386.rpm prior to sendmail-doc-8.11.6-13.i386.rpm OpenLinux 3.1 Workstation prior to sendmail-8.11.6-13.i386.rpm prior to sendmail-cf-8.11.6-13.i386.rpm prior to sendmail-doc-8.11.6-13.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.
