Reading more, this is a pretty scary bug.

Here is a link to the original security advisory:
http://www.us.debian.org/security/2008/dsa-1571

The detection tool was kinda tricky to figure out how to use so
more info is here:
http://wiki.debian.org/SSLkeys#head-45e521140d6b8f2a0f96a115a5fc616c4f1baf0b

So running the detection script, using myself as an example, you
want to see something like this:
$ perl dowkd.pl user
notice: creating database, please wait
/home/me/.ssh/known_hosts:1: 2048 bits DSA key not recommended
/home/me/.ssh/known_hosts:9: 2048 bits DSA key not recommended
/home/me/.ssh/known_hosts:10: 2048 bits DSA key not recommended
/home/me/.ssh/known_hosts:36: 2048 bits DSA key not recommended
/home/me/.ssh/known_hosts:90: 512 bits DSA key not recommended
/home/me/.ssh/known_hosts:93: 2048 bits DSA key not recommended
/home/me/.ssh/known_hosts:97: 2048 bits DSA key not recommended
summary: keys found: 99, weak keys: 0

A good write up here as well:
