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 bug in Last Pass affecting version 4.1.42 (Chrome&FF). RCE if you use “Binary Component”, otherwise they can steal codes accesss. I am preparing a full report.
