REDHAT-BUG-2295010: High severity gorilla schema vulnerability

gorilla/schema converts structs to and from form values. Prior to version 1.4.1 Running schema.Decoder.Decode() on a struct that has a field of type []struct{...} opens it up to malicious attacks regarding memory allocations, taking advantage of the sparse slice functionality. Any use of schema.Decoder.Decode() on a struct with arrays of other structs could be vulnerable to this memory exhaustion vulnerability. Version 1.4.1 contains a patch for the issue.
