Published January 03, 2017 | Updated February 2, 2017

The Android Security Bulletin contains details of security vulnerabilities affecting Android devices. Alongside the bulletin, we have released a security update to Google devices through an over-the-air (OTA) update. The Google device firmware images have also been released to the Google Developer site. Security patch levels of January 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 on December 05, 2016 or earlier. 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 that could enable remote code execution on an affected device through multiple methods such as email, web browsing, and MMS when processing media files. 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 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 service mitigations section for details on the Android security platform protections and service protections such as SafetyNet, which improve the security of the Android platform.

We encourage all customers to accept these updates to their devices.

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: 2017-01-01 : Partial security patch level string. This security patch level string indicates that all issues associated with 2017-01-01 (and all previous security patch level strings) are addressed. 2017-01-05 : Complete security patch level string. This security patch level string indicates that all issues associated with 2017-01-01 and 2017-01-05 (and all previous security patch level strings) are addressed.

Supported Google devices will receive a single OTA update with the January 05, 2017 security patch level.

Security vulnerability summary

The tables below contains a list of security vulnerabilities, the Common Vulnerability and Exposures ID (CVE), the assessed severity, and whether or not Google 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 if 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.

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 2017-01-01 or later address all issues associated with the 2017-01-01 security patch level.

Security patch levels of 2017-01-05 or later address all issues associated with the 2017-01-05 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]:[2017-01-01]

[ro.build.version.security_patch]:[2017-01-05]

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 January 1, 2017 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 January 5, 2017 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. How do I determine which Google devices are affected by each issue?

In the 2017-01-01 and 2017-01-05 security vulnerability details sections, each table has an Updated Google devices column that covers the range of affected Google devices updated for each issue. This column has a few options:

All Google devices : If an issue affects All and Pixel devices, the table will have "All" in the Updated Google devices column. "All" encapsulates the following supported devices: Nexus 5X, Nexus 6, Nexus 6P, Nexus 9, Android One, Nexus Player, Pixel C, Pixel, and Pixel XL.

: If an issue affects All and Pixel devices, the table will have "All" in the Updated Google devices column. "All" encapsulates the following supported devices: Nexus 5X, Nexus 6, Nexus 6P, Nexus 9, Android One, Nexus Player, Pixel C, Pixel, and Pixel XL. Some Google devices : If an issue doesn't affect all Google devices, the affected Google devices are listed in the Updated Google devices column.

: If an issue doesn't affect all Google devices, the affected Google devices are listed in the Updated Google devices column. No Google devices: If no Google devices running the latest available version of Android are affected by the issue, the table will have "None" in the Updated Google devices column.

4. What do the entries in the references column map to?

Entries under the References column of the vulnerability details table may contain a prefix identifying the organization to which the reference value belongs. These prefixes map as follows:

Prefix Reference A- Android bug ID QC- Qualcomm reference number M- MediaTek reference number N- NVIDIA reference number B- Broadcom reference number
