TOP VULNERABILITY THIS WEEK: LastPass Addresses Security Flaw Identified by Researcher Tavis Ormandy


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.

Title: Google Releases Monthly Android Security Bulletin
Description: Google has released their monthly Android security bulletin to address vulnerabilities within the mobile OS. This month’s bulletin is divided into two patch levels to “provide Android partners with the flexibility” to address common Android components shared across all Android devices. In total, 102 vulnerabilities were addressed across both patch levels with 3 of them being Critical Mediaserver bugs that could allow arbitrary code execution. Another 3 dozen or so vulnerabilities within Qualcomm components were also addressed in the 2015-08-05 patch level.
