New Mac OS X Exploit?

The UK's IT Week reports on a possible new Mac OS X exploit. A proof of concept appears on the Info-pull.com website, claiming that corrupted UDTO HFS+ image structures are vulnerable to denial of service attacks. If true, this same issue may affect FreeBSD installations. The article suggests disabling "open 'safe files' after downloading", which realistically speaking you've probably already done a long time ago if you've been worried about possible OS X attacks.
