Google releases June 2016 Android Security Bulletin and Nexus Images

Last updated:

Google has released the June 2016 Android Security Bulletin. Partners have had access to the warnings in this month’s bulletin since May 2 or earlier.

Alongside the bulletin, Google have released a security update to Nexus devices through an over-the-air (OTA) update. The Nexus firmware images have also been released to the Google Developer site. Source code patches for these issues will be released to the Android Open Source Project (AOSP) repository in the next 48 hours.

The table below contains a list of security vulnerabilities, the Common Vulnerability and Exposures ID (CVE), their assessed severity and whether or not Nexus devices are affected.

The severity assessment is based on the effect that exploiting the vulnerability would possibly have on an affected device, assuming the platform and service mitigations are disabled for development purposes or successfully bypassed.

Android and Google Service Mitigations

This is a summary of the mitigations provided by the Android security platform and service protections such as SafetyNet. These capabilities reduce the likelihood that security vulnerabilities could be successfully exploited on Android.

  • Exploitation for many issues on Android is made more difficult by enhancements in newer versions of the Android platform. We encourage all users to update to the latest version of Android where possible.
  • The Android Security team actively monitors for abuse with Verify Apps and SafetyNet, which are designed to warn users about Potentially Harmful Applications. Verify Apps is enabled by default on devices with Google Mobile Services, and is especially important for users who install applications from outside of Google Play. Device rooting tools are prohibited within Google Play, but Verify Apps warns users when they attempt to install a detected rooting application—no matter where it comes from. Additionally, Verify Apps attempts to identify and block installation of known malicious applications that exploit a privilege escalation vulnerability. If such an application has already been installed, Verify Apps will notify the user and attempt to remove the detected application.
  • As appropriate, Google Hangouts and Messenger applications do not automatically pass media to processes such as Mediaserver.
