Android Security Bulletin—August 2020
Published August 3, 2020 | Updated August 4, 2020
 
The Android Security Bulletin contains details of security vulnerabilities affecting Android devices. Security patch levels of 2020-08-05 or later address all of these issues. To learn how to check a device's security patch level, see Check and update your Android version.
 
Android partners are notified of all issues at least a month before publication. Source code patches for these issues will be released to the Android Open Source Project (AOSP) repository in the next 48 hours. We will revise this bulletin with the AOSP links when they are available.
 
The most severe of these issues is a high security vulnerability in the Framework component that could enable a remote attacker using a specially crafted file to execute arbitrary code within the context of an unprivileged process. 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 turned off for development purposes or if successfully bypassed.
 
Refer to the Android and Google Play Protect mitigations section for details on the Android security platform protections and Google Play Protect, which improve the security of the Android platform.
 
Note: Information on the latest over-the-air update (OTA) and firmware images for Google devices is available in the August 2020 Pixel Update Bulletin.

Android and Google service mitigations
This is a summary of the mitigations provided by the Android security platform and service protections such as Google Play Protect. 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 through Google Play Protect and warns users about Potentially Harmful Applications. Google Play Protect is enabled by default on devices with Google Mobile Services, and is especially important for users who install apps from outside of Google Play.
