Android Security Bulletin—October 2016

Description

The Android Security Bulletin contains details of security vulnerabilities affecting Android devices. Alongside the bulletin, we have released a security update to Nexus devices through an over-the-air (OTA) update. The Nexus firmware images have also been released to the [Google Developer site](<https://developers.google.com/android/nexus/images>). Security Patch Levels of October 05, 2016 or later address these issues. Refer to the [documentation](<https://support.google.com/nexus/answer/4457705#nexus_devices>) to learn how to check the security patch level. Supported Nexus devices will receive a single OTA update with the October 05, 2016 security patch level. Partners were notified about the issues described in the bulletin on September 06, 2016 or earlier. Where applicable, source code patches for these issues have been released to the Android Open Source Project (AOSP) repository. This bulletin also includes links to patches outside of AOSP. The most severe of these issues are Critical security vulnerabilities in device-specific code that could enable remote code execution within the context of the kernel, leading to the possibility of a local permanent device compromise, which may require reflashing the operating system to repair the device. 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](<https://developer.android.com/training/safetynet/index.html>), 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: * **2016-10-01**: Partial security patch level string. This security patch level string indicates that all issues associated with 2016-10-01 (and all previous security patch level strings) are addressed. * **2016-10-05**: Complete security patch level string. This security patch level string indicates that all issues associated with 2016-10-01 and 2016-10-05 (and all previous security patch level strings) are addressed. * Supported Nexus devices will receive a single OTA update with the October 05, 2016 security patch level. ## 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](<http://static.googleusercontent.com/media/source.android.com/en//security/reports/Google_Android_Security_2015_Report_Final.pdf>), which are designed to warn users about [Potentially Harmful Applications](<http://static.googleusercontent.com/media/source.android.com/en//security/reports/Google_Android_Security_PHA_classifications.pdf>). Verify Apps is enabled by default on devices with [Google Mobile Services](<http://www.android.com/gms>), 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. ## Acknowledgements We would like to thank these researchers for their contributions: * Andre Teixeira Rizzo: CVE-2016-3882 * Andrea Biondo: CVE-2016-3921 * Daniel Micay of Copperhead Security: CVE-2016-3922 * [Dmitry Vyukov](<https://github.com/google/syzkaller>) of Google: CVE-2016-7117 * dosomder: CVE-2016-3931 * Ecular Xu (徐健) of Trend Micro: CVE-2016-3920 * Gengjia Chen ([@chengjia4574](<https://twitter.com/chengjia4574>)) and [pjf](<http://weibo.com/jfpan>) of IceSword Lab, Qihoo 360 Technology Co.

How do I determine if my device is updated to address these issues? ** Security Patch Levels of 2016-10-01 or later address all issues associated with the 2016-10-01 security patch string level. Security Patch Levels of 2016-10-05 or later address all issues associated with the 2016-10-05 security patch string level. Refer to the [help center](<https://support.google.com/nexus/answer/4457705>) for instructions on how to check the security patch level. Device manufacturers that include these updates should set the patch string level to: [ro.build.version.security_patch]:[2016-10-01] or [ro.build.version.security_patch]:[2016-10-05]. **2\. Why does this bulletin have two security patch level strings?** This bulletin has two security patch level strings 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 string. Devices that use the security patch level of October 5, 2016 or newer must include all applicable patches in this (and previous) security bulletins. Devices that use the October 1, 2016 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. **3\. How do I determine which Nexus devices are affected by each issue?** In the 2016-10-01 and 2016-10-05 security vulnerability details sections, each table has an _Updated Nexus devices_ column that covers the range of affected Nexus devices updated for each issue. This column has a few options: * **All Nexus devices**: If an issue affects all Nexus devices, the table will have “All Nexus” in the _Updated Nexus devices_ column. “All Nexus” encapsulates the following [supported devices](<https://support.google.com/nexus/answer/4457705#nexus_devices>): Nexus 5, Nexus 5X, Nexus 6, Nexus 6P, Nexus 9, Android One, Nexus Player and Pixel C. * **Some Nexus devices**: If an issue doesn’t affect all Nexus devices, the affected Nexus devices are listed in the _Updated Nexus devices_ column. * **No Nexus devices**: If no Nexus devices running Android 7.0 are affected by the issue, the table will have “None” in the _Updated Nexus 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 ## Revisions * October 03, 2016: Bulletin published. * October 04, 2016: Bulletin revised to include AOSP links and update attributions for CVE-2016-3920, CVE-2016-6693, CVE-2016-6694, CVE-2016-6695, and CVE-2016-6696.
