- 漏洞讨论

Caldera OpenServer includes a set of utilities to report CPU usage status information. The utilities are sar, mpsar, cpusar and sadc. They are installed setuid mem by default.

These utilities are susceptible to a buffer overflow related to processing of the argument to the '-o' command-line option. This condition may be exploited by local attackers to obtain effective userid mem privileges.
