Process
=====
The Mbed TLS project uses the TrustedFirmware.org security incident handling process as described [[ https://developer.trustedfirmware.org/w/collaboration/security_incident_process/reporting/ | here ]]. There are some of caveats to the process for this project, as listed below:
# The project currently does not have any registered ESSes and so there is no primary embargo period.
# The project contains strong cryptography software and to comply with export control restrictions, must only distribute software publicly. As a result, security fixes cannot be shared privately with Trusted Stakeholders, although other vulnerability information can be.
# The nature of this project often means that security fixes reveal enough information for a skilled attacker to re-construct the originally reported exploit. This combined with the previous caveat means we often expect to have to withhold security fixes until the public disclosure date.
# This project is subject to a lot of scrutiny by security researchers who often have their own disclosure timelines when reporting vulnerabilities. As a result, the default 90 days public embargo period may often not apply.
Advisories
=======
Mbed TLS security advisories are currently listed in the old Mbed TLS website [[ https://tls.mbed.org/security | here ]]. These will be migrated to TrustedFirmware.org in due course.
