Descriptions

This vulnerability allows local attackers to escalate privileges on vulnerable installations of Joyent SmartOS release-20170803-20170803T064301Z. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the DTrace DOF files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated object. An attacker can leverage this vulnerability to execute code under the context of the host OS. Was ZDI-CAN-5106.

Esta vulnerabilidad permite que los atacantes locales escalen privilegios en instalaciones vulnerables de Joyent SmartOS release-20170803-20170803T064301Z. En primer lugar, un atacante debe obtener la capacidad de ejecutar código de bajos privilegios en el sistema objetivo para explotar esta vulnerabilidad. Este error en concreto existe en los archivos DTrace DOF. El problema deriva de la falta de validación correcta de información proporcionada por el usuario, lo que puede dar como resultado la escritura más allá del final de un objeto asignado. Un atacante podría aprovecharse de esta vulnerabilidad para ejecutar código en el contexto del host del sistema operativo. Anteriormente era ZDI-CAN-5106.
