CVE-2018-1171

Estado: ModificadaAlta (7)—

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.

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.
