maxv 8fdfc138ab Fix buffer overflows. sc_{o,f}len are controlled by the USB device. By 
crafting the former the device can leak stack data. By crafting the latter
the device can overwrite the stack. The combination of the two means the
device can ROP the kernel and obtain code execution (demonstrated with an
actual exploit over vHCI).

Truncate the lengths to the size of the buffers, and also drop sc_ilen
since it is unused. Patch tested with vHCI+kASan.

NetBSD

NetBSD is a free, fast, secure, and highly portable Unix-like Open Source operating system. It is available for a wide range of platforms, from large-scale servers and powerful desktop systems to handheld and embedded devices.

Building

You can cross-build NetBSD from most UNIX-like operating systems. To build for amd64 (x86_64), in the src directory:

./build.sh -U -u -j4 -m amd64 -O ~/obj release

Additional build information available in the BUILDING file.

Binaries

Testing

On a running NetBSD system:

cd /usr/tests; atf-run | atf-report

Troubleshooting

Latest sources

To fetch the main CVS repository:

cvs -d anoncvs@anoncvs.NetBSD.org:/cvsroot checkout -P src

To work in the Git mirror, which is updated every few hours from CVS:

git clone https://github.com/NetBSD/src.git
