smcFanControl main() buffer overflow
| smcfancontrol-main-bo (46551) |  High Risk |
Description:
smcFanControl is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the main() of the "smc" setuid root binary. By sending an overly long "-k" option, a local attacker could overflow a buffer and execute arbitrary code on the system with SYSTEM privileges or cause the application to crash.
