Title says it all. I can't really sugar coat this one. Tumblr and Flickr may also be impacted as well. 1 billion accounts may be compromised.

Also, change passwords for other sites if you use the same password there as your Yahoo account.

Update: Appears Tumblr is safe based on Yahoo!'s security notice. Still a good practice to periodically change passwords.
