Security notifications or problems should be reported in GitLab by filing an issue and marking it as confidential before submitting it (if you follow the link on the left the confidential checkbox should already be ticked).

If you have patches, please attach them to the confidential issue and not via a merge requests, as merge requests are always public immediately.

The GStreamer project encourages responsible disclosure of security issues.

Distributors please note that this is not an exhaustive or comprehensive list of security-relevant issues affecting past releases, but merely a list of security issues filed as such by third parties. Fixes that may be security relevant are also landed as part of routine bug-fixing and development activity, and as such we encourage distributors to upgrade to our latest bug-fix releases whenever possible.
