Beware of using the Last Pass: Tavis Ormandy, one of the most prolific members of Google's Project Zero Team, revealed a new security issue at LastPass.
Ormandy said there was a exploit but has not made it public at the moment. Let's remind that Google Project Zero researchers report the vulnerabilities first to the directly interested companies developing the affected products. Companies have 90 days to insure their product, usually by developing a new version, otherwise researchers are releasing the exploit.
The information is very small until now, as Ormandy has made available through Twitter:
Oops, new LastPass bug that affects 4.1.42 (Chrome & FF). RCE if you use the "Binary Component", otherwise can steal pwds. Full report on way. pic.twitter.com/y92vm3Ibxd

Αναφέρει ότι η τελευταία έκδοση του LastPass για το Google Chrome και τον Firefox (έκδοση 4.1.42), και ότι το exploit μπορεί να χρησιμοποιηθεί για απομακρυσμένη εκτέλεση κώδικα ή την theft of passwords.
It later revealed that it has a fully functional exploit that it does not display messages on Windows, and it's just two lines of code. He also noted that the exploit could work on other platforms.

Shortly after, the company published a second message stating that the issue was resolved.
The issue mentioned by Tavis Ormandy has been resolved. We will provide additional clarifications to our blog soon.
According to the tweet, if you use the Last Pass application, you do not have to do anything except waiting for the announcement of the solution that corrects vulnerability from the company.
