Lind Build Status Build Status

Lind is a single-process sandbox that provides an option to safely execute programs and control its resource (network, file, memory, cpu, etc.) usage at the process granularity. Lind executes applications in an isolated environment from the rest of the applications in the system, and thus limits the damage of bugs or security flaws in the application.

For high level documentation, please go to the main documentation for the project.

Lind is currently a work in progress, please bear with us while features are being implemented.

Building with Docker

Base and pre-built docker images for the SDK toolchain can be fetched from the Docker Hub Lind repository at securesystemslab/lind with docker pull securesystemslab/lind.

You can either make run or start the container yourself using:

docker pull securesystemslab/lind
docker run --privileged --ipc=host --init --cap-add=SYS_PTRACE -it securesystemslab/lind /bin/bash

The --privileged option is so that /proc is writable, the --ipc=host option is needed to avoid mounting /dev/shm with noexec (NaCl needs to be able to execute mmap()'d sections of /dev/shm) and the --cap-add=SYS_PTRACE allows debugging with applications that use ptrace() such as gdb.

Security Issues and Bugs

Security issues can be reported by emailing

At a minimum, the report must contain the following:

  • Description of the vulnerability.
  • Steps to reproduce the issue.

Optionally, reports that are emailed can be encrypted with PGP. You should use PGP key fingerprint E9C0 59EC 0D32 64FA B35F 94AD 465B F9F6 F8EB 475A.

Please do not use the GitHub issue tracker to submit vulnerability reports. The issue tracker is intended for bug reports and to make feature requests.
