Between server-side fixes and updated extensions, the issues have been addressed.

Last year Google Project Zero researcher Tavis Ormandy quickly found some "obvious" security problems in the popular password manager LastPass, and now he's done it again. Last week Ormandy mentioned finding an exploit in one version of its extension for Firefox, before following that up with a new bug that affected both Chrome and Firefox, and finally a third vulnerability that could allow "stealing passwords for any domain."

The first vulnerability has apparently not been addressed yet, which Ormandy mentions may be the result of Mozilla needing time to review the updated extension before pushing it to users. Based on his tweet, it could reveal a user's password, but not all of the details have been revealed yet.

The second issue could be more serious, with the ability to steal a user's passwords or, if the binary version of the extension is installed, run any code the attacker tells it to (in an example, Ormandy causes the target's computer to open a Calculator program.) According to LastPass the issue has been resolved, although a promised follow-up blog post with more details has yet to appear.

There's even less info available about the latest vulnerability identified (updated -- see below.)

The pace of these discoveries and the lack of information from LastPass is certainly troubling, although using a password manager to maintain unique passwords can help protect you from being hacked. We've contacted the company and will update this post with any news, however, it may be wise to disable the affected browser extensions for now. If you're suddenly looking for another service to store your important login information, Tavis (who makes a habit of poking holes in security products) suggested KeePass, a manager that doesn't use browser extensions to keep a layer of security between websites and your vault.

Update: LastPass has responded with a blog post. Regarding the bug above that affected clients in Chrome, Firefox and Edge, the company says it applied a server-side workaround. As far as the bug for Firefox 4.1.35a, the company says this has been addressed in a new version pushed last night, so users of that browser should make sure they've updated to 4.136a.

Finally, the bug Ormandy noted in the older (and soon to be deprecated) version of the LastPass Firefox extension is fixed in a new update, so users of that version should update to 3.3.6, via the browser's built-in system.
