Are there any outstanding critical security issues for Sql Server 2000?

Are there any outstanding (unpatched) security issues for Sql Server 2000?

This isn't really for me: I moved on from Sql Server 2000 long ago. However, when answering questions here and on Stack Overflow, I'm in the habit of leaving a comment like the one at this question whenever coming across a Sql Server 2000 question. If you don't want to follow the link, it goes something like this:

Sql Server 2000 is end of life. It no longer gets any patches... not even critical security patches. It's irresponsible to continue using it. Convincing management to upgrade is job #1.

Aide from it being, well, Sql Server 2000, how much an issue is this really? In the years since Sql Server 2000 went EOL, has anything big come up I could point to as a more concrete issue?
