We take the security of
lemur seriously. The following are a set of
policies we have adopted to ensure that security issues are addressed in a
Reporting a security issue¶
We ask that you do not report security issues to our normal GitHub issue tracker.
If you believe you’ve identified a security issue with
report it to
Once you’ve submitted an issue via email, you should receive an acknowledgment within 48 hours, and depending on the action to be taken, you may receive further follow-up emails.
At any given time, we will provide security support for the master branch as well as the 2 most recent releases.
Our process for taking a security issue from private discussion to public disclosure involves multiple steps.
Approximately one week before full public disclosure, we will send advance

- The steps we will be taking to remedy the issue.
- The patches, if any, that will be applied to
- The date on which the
lemurteam will apply these patches, issue new releases, and publicly disclose the issue.
Simultaneously, the reporter of the issue will receive notification of the date on which we plan to make the issue public.
On the day of disclosure, we will take the following steps:
- Apply the relevant patches to the
lemurrepository. The commit messages for these patches will indicate that they are for security issues, but will not describe the issue in any detail; instead, they will warn of upcoming disclosure.
- Issue the relevant releases.
If a reported issue is believed to be particularly time-sensitive – due to a known exploit in the wild, for example – the time between advance notification and public disclosure may be shortened considerably.
The list of people and organizations who receives advanced notification of
security issues is not, and will not, be made public. This list generally
consists of high-profile downstream distributors and is entirely at the
discretion of the
