We aim to keep the latest images up-to date and free of any potential security problems. Please feel free to reach out if you have questions or believe that you found a potential security issue.
To report a vulnerability, email the maintainers, albert+dockerfiles@zeitkraut.de and caleb@alerque.com.
The pandoc manual has a section entitled A note on security, which describes some security guarantees pandoc does NOT make. Its also a good resource for users of pandoc Docker images.
Also note that outside this repo, only the most recent version of pandoc is supported with security updates. So while the other software in an image may be patched to the latest level, issues in pandoc itself may not have been fixed in older images.
