A buffer overflow privilege escalation vulnerability in Trend Micro Maximum Security (Consumer) 2018 could allow a local attacker to escalate privileges on vulnerable installations due to a flaw within processing of IOCTL 0x22205C by the tmnciesc.sys driver. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
