Indeed, CVE and any other refined vulnerability information source is
chock full of open source products on SourceForge that have the most
obvious security holes possible, and let's not forget the open source
products that have gotten a bad reputation such as PHP-Nuke and Sendmail.
Insecure programming is universal.

Seems to, yes, based on statistics of publicly reported vulns.
Unfortunately I can't remember the studies at the moment :(
