The vulnerability exists because a component of the snmp agent service that interprets incoming commands contains an unchecked buffer a temporary data storage area that has a limited capacity 出現此漏洞的原因是,解釋傳入命令的snmp代理服務組件包含未檢查的緩沖區具有有限容量的臨時數據存儲區。
At the same time the clock chip pcf8563 and serial eeprom chip csi24c01 with reset and wdt circuit of i2c bus are used hi the system . they have not only provided the non - volatility data storage area , the supervision ability of power supply and mcu and the rtc , and its i2c bus structure has been simplified the circuit design 同時在系統中還使用了護c總線結構的時鐘芯片pcf8563和內置reset 、 wdt電路的串行eeprom芯片csi24coi ,它們不僅提供了電源和微控制器的監控功能、不揮發性的數據存儲區、實時時鐘,而且其護c總線結構簡化了電路設計。
