Problem Description Davide Del Vecchio reported a buffer overflow in HP-UX that affected the disable command. This caused us to take a closer look at the enable and disable commands in SCO OpenServer. The system is designed to allow an administrator to give out subsystem privileges. If a user has been given the "lp" privilege, he could run enable/disable and possably gain root privileges. Regular users can't run enable and disable. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-1131 to this issue. 2. Vulnerable Supported Versions System Binaries ---------------------------------------------------------------------- OpenServer 5.0.6 /usr/bin/enable OpenServer 5.0.7 /usr/bin/enable 3. Solution The proper solution is to install the latest packages. 4.
