A simple denial-of-service vulnerability is far from the worst-case scenario... If the code has any sort of cryptographic functionality, if it generates random passwords, or anything of that sort, then weak random numbers can lead to far worse than that, as they'll give an attacker a much better chance of guessing any randomly-generated values (such as session keys or random passwords).

Of course, if you're doing anything along those lines, I sincerely hope that you'd be using a properly-installed perl rather than one copied onto an SD card, so this is unlikely to be an issue in practice.
