The easiest solution is to add the following code to your CSS:

.gist-data{
    height:250px; // Any height
    overflow-y: visible;
}

This will limit the height of the gist's container, I tried other wrappers around it and this was the first one to limit the height.

Depending on specificity, you may need to add !important in your styles.

One WordPress project which provides that kind of feature would be "Embed GitHub Gist / Gist height (7 posts)".

I wanted to add a gist height for really long gists that would result in a scrollbar for the embed.
Here's the patch to achieve this for the current trunk using a height parameter to the shortcode.

The most recent version is at this project.

Some of that work might have been included in "dflydev/embed-github-gist".
