I don't see the point in knowing how many days ago the security fix was published, since I'd really care if my machine is running a kernel that contains the fix.

So I can see how I might want to know which branches (and/or tags) in my repository contain the security fix. And this is pretty easy,

#!/bin/sh
fix="$(git-rev-parse --verify $1)"
git ls-remote . | while read sha ref ; do
    [ "$fix" == "$(git-merge-base "$fix" "$sha")" ] && echo $ref
done

Of course this could be cleaned up and extended quite a bit, possibly allowing a user to specify if he cares about only branches, or tags or some specific branch.
