CVE-2017-12718 Information

Description

A Classic Buffer Overflow issue was discovered in Smiths Medical Medfusion 4000 Wireless Syringe Infusion Pump Version 1.1 1.5 and 1.6. A third-party component used in the pump does not verify input buffer size prior to copying leading to a buffer overflow allowing remote code execution on the target device. The pump receives the potentially malicious input infrequently and under certain conditions increasing the difficulty of exploitation.
