This document attempts to describe the processes through which sensitive security relevant bugs can be responsibly disclosed to the SELinux userspace project and how the project maintainers should handle these reports. Just like the other SELinux userspace process documents, this document should be treated as a guiding document and not a hard, unyielding set of regulations; the bug reporters and project maintainers are encouraged to work together to address the issues as best they can, in a manner which works best for all parties involved.
For serious problems or security vulnerabilities in the SELinux kernel code please refer to the SELinux Kernel Subsystem Security Policy in the link below:
Problems with the SELinux userspace that are not suitable for immediate public disclosure should be emailed to the current SELinux userspace maintainers, the list is below. We typically request at most a 90 day time period to address the issue before it is made public, but we will make every effort to address the issue as quickly as possible and shorten the disclosure window.
Upon disclosure of a bug, the maintainers should work together to investigate the problem and decide on a solution. In order to prevent an early disclosure of the problem, those working on the solution should do so privately and outside of the traditional SELinux userspace development practices. One possible solution to this is to leverage the GitHub “Security” functionality to create a private development fork that can be shared among the maintainers, and optionally the reporter. A placeholder GitHub issue may be created, but details should remain extremely limited until such time as the problem has been fixed and responsibly disclosed. If a CVE, or other tag, has been assigned to the problem, the GitHub issue title should include the vulnerability tag once the problem has been disclosed.
Whenever possible, responsible reporting and patching practices should be followed, including notification to the linux-distros and oss-security mailing lists.
