Buffer Overflow with libopenhmd0 (0.2.0-3)

[WayneKeenan]

Hi,

I going to be investigating a buffer overflow issue that I'm seeing on libopenhmd0 (0.2.0-3) on RaspberryPi Raspbian Stretch.

I see the issue occurs with your Cython based bindings and also a small ctypes one I wrote.

Before I jet of into it I wondered if you had seen it before?

I also made a minor tweak to get the code to compile against libopenhmd0 (0.2.0-3) and added some Pi notes.

The issue for reference : https://github.com/WayneKeenan/python-vrzero/issues/7

The tweak (Would you like a PR for it?): https://github.com/WayneKeenan/python-rift/commit/fa23b59a716e4509f7d23f0b754705d696d794f5

Thanks Wayne

Hi,

I just wanted to let you know that I resolved this buffer overflow in my hmd.py helper.
The key centres around adding this OpenHMD API call to get a valid HMD device: https://github.com/WayneKeenan/python-vrzero/blob/SonyPSVR_WIP/vrzero/hmd.py#L36

Hope it helps, Wayne
