Security Policy

To report a vulnerability see "Reporting a Vulnerability" below.

Security Incident Policy

Security bug reports are treated with special attention and are handled
differently from normal bugs. In particular, security sensitive bugs are not
handled in public but in private. Information about the bug and access to it
is restricted to people in the security group, the individual engineers that
work on fixing it, and any other person who needs to be involved for organisational
reasons. The process is handled by the security team, which decides on the people
involved in order to fix the issue. It is also guaranteed that the person reporting
the issue has visibility into the process of fixing it. Any security issue gets
prioritized according to its security rating. The issue is opened up to the public
in coordination with the release schedule and the reporter.

Disclosure Policy

Everyone involved in the handling of a security issue - including the reporter -
is required to adhere to the following policy. Any information related to
a security issue must be treated as confidential and only shared with trusted
partners if necessary, for example to coordinate a release or manage exposure
of clients to the issue. No information must be disclosed to the public before
the embargo ends. The embargo time is agreed upon by all involved parties. It
should be as short as possible without putting any users at risk.

Supported Versions

Only the most recent version of the GRUB is supported.

Reporting a Vulnerability

The security report should be encrypted with the PGP keys and sent to ALL email
addresses listed below. Every vulnerability report will be assessed within
72 hours of receiving it. If the outcome of the assessment is that the report
describes a security issue, the report will be transferred into an issue on the
internal vulnerability project for further processing. The reporter is updated
on each step of the process.

While there's currently no bug bounty program we appreciate every report.
