A major announcement on the FreeBSD mailing list landed earlier today:
URGENT: RNG broken for last 4 months in the -current branch [...] This means most/all keys generated may be predictable and must be regenerated. This includes, but not limited to, ssh keys and keys generated by openssl. This is purely a kernel issue, and a simple kernel upgrade w/ the patch is sufficient to fix the issue.
Various security companies and blogs are already reporting duplicate keys spotted in the wild. So, patch your systems!.
[Updates: (1) This pertains to the '-current' branch which is not recommended for use on production systems. (2) The statement about "duplicate keys" was in the original submission, but lacks confirmation. If you can confirm/deny, please reply in the comments with a link to the source.]

Apparently this issue only affects people running the current version (unstable/testing branch). If you're on 10.1 (the latest production release) you should be fine.
