We have just released a very important security update for our iPhone and iPad apps addressing an issue that allowed passwords to be compromised in certain circumstances. Please download the update now.

If you’ve been using these apps, you should also update your password on Tumblr and anywhere else you may have been using the same password.

That does not sound good.
