There was a problem hiding this comment.
It looks like tests for all the elaborate error messages are missing? Like option / array combinations etc.

There's still a bit more work (testing) needed as I noticed few mistakes in params when extending the bug81713.phpt . I will need to cover all functions to be sure that there aren't more mistakes. So far I have got cms and pkcs7 covered as well as few others. Will extend it further to cover the rest. |

It introduces a single function to check file paths passed to OpenSSL functions. It expands the path, check null bytes and finally does an open basedir check.
