Published September 5, 2017 | Updated October 5, 2017

The Android Security Bulletin contains details of security vulnerabilities affecting Android devices. Security patch levels of September 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 severity 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.

Announcements

This bulletin has two security patch level strings to provide Android partners with the flexibility to more quickly fix a subset of vulnerabilities that are similar across all Android devices. See Common questions and answers for additional information: 2017-09-01 : Partial security patch level string. This security patch level string indicates that all issues associated with 2017-09-01 (and all previous security patch level strings) are addressed. 2017-09-05 : Complete security patch level string. This security patch level string indicates that all issues associated with 2017-09-01 and 2017-09-05 (and all previous security patch level strings) are addressed.



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.

Common questions and answers

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.

Security patch levels of 2017-09-01 or later address all issues associated with the 2017-09-01 security patch level.

Security patch levels of 2017-09-05 or later address all issues associated with the 2017-09-05 security patch level and all previous patch levels.

Device manufacturers that include these updates should set the patch string level to:

[ro.build.version.security_patch]:[2017-09-01]

[ro.build.version.security_patch]:[2017-09-05]

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.

Devices that use the 2017-09-01 security patch level must include all issues associated with that security patch level, as well as fixes for all issues reported in previous security bulletins.

Devices that use the security patch level of 2017-09-05 or newer must include all applicable patches in this (and previous) security bulletins.

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.
