Problem Description Requesting a map that doesn't exist will cause a memory leak in the server. 2. Vulnerable Supported Versions System Package ---------------------------------------------------------------------- OpenLinux 3.1.1 Server prior to nis-client-2.0-23.i386.rpm prior to nis-server-2.0-23.i386.rpm OpenLinux 3.1.1 Workstation prior to nis-client-2.0-23.i386.rpm OpenLinux 3.1 Server prior to nis-client-2.0-23.i386.rpm prior to nis-server-2.0-23.i386.rpm OpenLinux 3.1 Workstation prior to nis-client-2.0-23.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.
