Description
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 SMB_IOC_SVCENUM IOCTL. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length, heap-based buffer. An attacker can leverage this vulnerability to execute code under the context of the host OS. Was ZDI-CAN-4983.
