After reporting the problems with OpenSSL, which has been nicknamed 'HeartBleed', 2 contributors have forward articles on why you should change your passwords.
I always believed Mojang would keep my details safe, now I realise they are not in control of their own data. Mojang/Minecraft passwords should be changed immediately
The fallout from the Heartbleed bug is hitting the mainstream. The BBC has an article headlined "Public urged to reset all passwords".
Bruce Schneier calls it "catastrophic", giving this advice to sysadmins: "After you patch your systems, you have to get a new public/private key pair, update your SSL certificate, and then change every password that could potentially be affected." He also links to a webpage that will let you test servers for the bug, and an article on Ars Technica discussing the bug.
