The Android Security Bulletin contains details of security vulnerabilities affecting Android devices. Security patch levels of August 05, 2017 or later address all of these issues. Refer to the Pixel and Nexus update schedule to learn how to check a device’s security patch level.
Partners were notified of the issues described in the bulletin at least a month ago. Source code patches for these issues have been released to the Android Open Source Project (AOSP) repository and linked from this bulletin. This bulletin also includes links to patches outside of AOSP.
The most severe of these issues is a critical security vulnerability in media framework that could enable a remote attacker using a specially crafted 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.
We encourage all customers to accept these updates to their devices.
Note: Information on the latest over-the-air update (OTA) and firmware images for Google devices is available in the Google device updates section.
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.
In the sections below, we provide details for each of the security vulnerabilities that apply to the 2017-08-01 patch level. Vulnerabilities are grouped under the component that they affect. There is a description of the issue and a table with the CVE, associated references, type of vulnerability, severity, and updated AOSP versions (where applicable). When available, we link the public change that addressed the issue to the bug ID, like the AOSP change list. When multiple changes relate to a single bug, additional references are linked to numbers following the bug ID.

This section answers common questions that may occur after reading this bulletin.
1. How do I determine if my device is updated to address these issues?
To learn how to check a device’s security patch level, read the instructions on the Pixel and Nexus update schedule.
Device manufacturers that include these updates should set the patch string level to:
2. Why does this bulletin have two security patch levels?
This bulletin has two security patch levels so that Android partners have the flexibility to fix a subset of vulnerabilities that are similar across all Android devices more quickly. Android partners are encouraged to fix all issues in this bulletin and use the latest security patch level.
Partners are encouraged to bundle the fixes for all issues they are addressing in a single update.
3. What do the entries in the Type column mean?
Entries in the Type column of the vulnerability details table reference the classification of the security vulnerability.
Abbreviation | Definition |
---|---|
RCE | Remote code execution |
EoP | Elevation of privilege |
ID | Information disclosure |
DoS | Denial of service |
N/A | Classification not available |
4. What do the entries in the References column mean?
Entries under the References column of the vulnerability details table may contain a prefix identifying the organization to which the reference value belongs.
Prefix | Reference |
---|---|
A- | Android bug ID |
QC- | Qualcomm reference number |
M- | MediaTek reference number |
N- | NVIDIA reference number |
B- | Broadcom reference number |
5. What does a * next to the Android bug ID in the References column mean?
Issues that are not publicly available have a * next to the Android bug ID in the References column. The update for that issue is generally contained in the latest binary drivers for Nexus devices available from the Google Developer site.
