- [client+server] Fernando Arnaboldi from IOActive found that strict filesystem permissions for various fwknop files are not verified. Added warnings whenever permissions are not strict enough, and ensured that files created by the fwknop client and server are only set to user read/write. - [client] Fernando Arnaboldi from IOActive found a local buffer overflow in --last processing with a maliciously constructed ~/.fwknop.run file. This has been fixed with proper validation of .fwknop.run arguments.
