Android Security Bulletin—May 2016

Published May 02, 2016 | Updated May 04, 2016

The Android Security Bulletin contains details of security vulnerabilities affecting Android devices. Alongside with 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. Security Patch Levels of May 01, 2016 or later address these issues (refer to the Nexus documentation for instructions on how to check the security patch level).

Partners were notified about the issues described in the bulletin on April 04, 2016 or earlier. Where applicable, source code patches for these issues have been released to the Android Open Source Project (AOSP) repository.

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.

We have had no reports of active customer exploitation or abuse of these newly reported issues. Refer to theAndroid 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

To reflect a broader focus, we renamed this bulletin (and all following in the series) to the Android Security Bulletin. These bulletins encompass a broader range of vulnerabilities that may affect Android devices, even if they do not affect Nexus devices.
We updated the Android Security severity ratings. These changes were the result of data collected over the last six months on reported security vulnerabilities and aim to align severities more closely with real world impact to users.

Security Vulnerability Summary

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

Security Vulnerability Details

In the sections below, we provide details for each of the security vulnerabilities listed in the Security Vulnerability Summary above. There is a description of the issue, a severity rationale, and a table with the CVE, associated bug, severity, updated Nexus devices, updated AOSP versions (where applicable), and date reported. When available, we will link the AOSP change that addressed the issue to the bug ID. When multiple changes relate to a single bug, additional AOSP references are linked to numbers following the bug ID.

Remote Code Execution Vulnerability in Mediaserver

During media file and data processing of a specially crafted file, a vulnerability in mediaserver could allow an attacker to cause memory corruption and remote code execution as the mediaserver process.

The affected functionality is provided as a core part of the operating system and there are multiple applications that allow it to be reached with remote content, most notably MMS and browser playback of media.

This issue is rated as Critical severity due to the possibility of remote code execution within the context of the mediaserver service. The mediaserver service has access to audio and video streams, as well as access to privileges that third-party apps could not normally access.

Common Questions and Answers

This section reviews answers to common questions that may occur after reading this bulletin.

1. How do I determine if my device is updated to address these issues?

Security Patch Levels of May 01, 2016 or later address these issues (refer to the Nexus documentation 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]:[2016-05-01]

2. How do I determine which Nexus devices are affected by each issue?

In the Security Vulnerability Details section, 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: Nexus 5, Nexus 5X, Nexus 6, Nexus 6P, Nexus 7 (2013), 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 theUpdated Nexus devices column.
No Nexus devices: If no Nexus devices are affected by the issue, the table will have “None” in the Updated Nexus devices column.

3. Why is CVE-2015-1805 included in this bulletin?

CVE-2015-1805 is included in this bulletin because the Android Security Advisory—2016-03-18 was published very close to the release of the April bulletin. Due to the tight timeline, device manufacturers were given the option to ship fixes from the Nexus Security Bulletin—April 2016, without the fix for CVE-2015-1805, if they used the April 01, 2016 Security Patch Level. It is included again in this bulletin as it must be fixed in order to use the the May 01, 2016 Security Patch Level.
