A heap-based buffer overflow privilege escalation vulnerability in Trend Micro ServerProtect for Linux 3.0 may allow an attacker to escalate privileges on affected installations.
An attacker must first obtain the ability to execute high-privileged code on the target in order to exploit this vulnerability.
