Watch out if you use Last Pass: Tavis Ormandy, one of its most prolific members teamGoogle's Project Zero has revealed a new security issue in 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, a new bug in Last Pass that affects version 4.1.42 (Chrome & FF). RCE if you use the "Binary Component", otherwise they may steal passwords. I am preparing a full report.
