Descriptions

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.

Una vulnerabilidad de escalada de privilegios de desbordamiento de búfer en la región heap de la memoria en Trend Micro ServerProtect para Linux versión 3.0, puede permitir a un atacante escalar privilegios en las instalaciones afectadas. Un atacante primero debe obtener la capacidad de ejecutar código muy privilegiado en el objetivo a fin de explotar esta vulnerabilidad

This vulnerability allows local attackers to escalate privileges on affected installations of Trend Micro ServerProtect. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the ioctlMod function. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the kernel.
