Description

alert http any any -> any any (msg:"File magic on GIF"; fileext:"GIF";sid:666; rev:1;)
- would not alert on a http downloaded file with
extension *.gif BUT it would on **.GIF (notice the upper case)

It would be beneficial if it could be made case insensitive - have the nocase keyword apply to it as well.

thanks

Merged https://github.com/inliniac/suricata/pull/820 to address this.

What it does it is change the matching of fileext:"exe"; to case insensitive unconditionally. This isn't ideal, but I would prefer overhauling the fileext and filename keywords completely to act like file_data.
