eval is evil.

[vStone]

If somebody would use quotes (or backticks) in some kind of message, using eval would allow them to execute malicious code on purpose or by accident.

IE: If any backticks are used, you would be able to reboot a server.

@vStone Thanks for your comment. Which eval do you mean? And more important: how would you advise me to work around it?

[vStone]

@aswen sorry about the late reply.

I think it would be this eval $(parse_yaml $lastrunfile $yaml_prefix) line.

Our catalog version uses the last commit message, whenever there is a quote in there, the check borks out with:
1: eval: Syntax error: Unterminated quoted string

We use a custom catalog version string as well. The following change parses the yaml data properly. I can send in a PR if you like me to.
