NOTABLE RECENT SECURITY ISSUES SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP
Title: LastPass Addresses Security Flaw Identified by Researcher Tavis Ormandy Description: LastPass has addressed a security flaw within the LastPass Firefox plugin, which was identified by Google Project Zero's Tavis Ormandy. Per the Project Zero bug, the LastPass Firefox plugin injects styling and event handlers into the web page "to create a privileged iframe." An attacker could have exploited this flaw to insert their own handler in a web page to "modify legitimate messages." LastPass has addressed the issue and pushed out an update for the Firefox plugin. Users can also manually update their plugins to ensure the patch is applied.
