It looks like you might have already taken care of this; it appears the s_nakamoto sourceforge account has been compromised:

Bitcoin project software development has moved to github, and we are self-hosting binary downloads. We kept the sourceforge project so old links continued to work, but considering the compromise of the s_nakamoto account the best course of action might be to entirely delete the sourceforge bitcoin project.
You can contact me at gavin@bitcoinfoundation.org with any questions or concerns.

Jeff Garzik pointed out we would need time to find another place for our mailing lists if the Bitcoin project is deleted.
Greetings,
We suspended s_nakamoto's account 2 hours and 17 minutes after the attacker gained access to that account.
After generating a list of changes made, confirming method of attack, and identifying no serious changes to project content, the project was restored to its pre-attack state, and the compromised user account was removed from the project.
Risk to the community is believed to be low, as file content wasn't modified.
Regards,
