OVERVIEW
Multiple security vulnerabilities have been identified in the Android
operating system prior to the 2019-08-05 patch level. [1]
IMPACT
Google has provided the following information about these vulnerabilities:
"The Android Security Bulletin contains details of security vulnerabilities
affecting Android devices. Security patch levels of 2019-08-05 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 critical security vulnerability in the
System component that could enable a remote attacker using a specially crafted
PAC file to execute arbitrary code within the context of a privileged 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.
We have had no reports of active customer exploitation or abuse of these newly
reported issues. 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 2019 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.
o 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.
o 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.
