<p><em>Published June 06, 2016 | Updated June 08, 2016</em></p>

<p>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
<a href="https://developers.google.com/android/nexus/images">Google Developer site</a>.
Security Patch Levels of June 01, 2016 or later address these issues. Refer
to the <a href="https://support.google.com/nexus/answer/4457705#nexus_devices">
Nexus documentation</a> to learn how to check the security patch level.</p>

<p>Partners were notified about the issues described in the bulletin on May 02,
2016 or earlier. Where applicable, source code patches for these issues have
been released to the Android Open Source Project (AOSP) repository.</p>

<p>The most severe issue 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.</p>

<p>We have had no reports of active customer exploitation or abuse of these newly
reported issues. Refer to the <a href="#mitigations">
Android and Google Service Mitigations</a> section for details on the
<a href="{@docRoot}security/enhancements/index.html">
Android security platform protections</a> and service protections such as
SafetyNet, which improve the security of the Android platform.</p>

<p>We encourage all customers to accept these updates to their devices.</p>

<h2 id=security_vulnerability_summary>Security Vulnerability Summary</h2>


<p>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
<a href="{@docRoot}security/overview/updates-resources.html#severity">
severity assessment</a> 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 successfully bypassed.</p>

<h2 id=mitigations>Android and Google Service Mitigations</h2>


<p>This is a summary of the mitigations provided by the
<a href="{@docRoot}security/enhancements/index.html">
Android security platform</a> and service protections, such as SafetyNet.
These capabilities reduce the likelihood that security vulnerabilities could
be successfully exploited on Android.</p>

<ul>
  <li> 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.
  <li> The Android Security team actively monitors for abuse with
       <a href="{@docRoot}security/reports/Google_Android_Security_2015_Report_Final.pdf">
       Verify Apps and SafetyNet</a>, which are designed to warn users about
       <a href="{@docRoot}security/reports/Google_Android_Security_PHA_classifications.pdf">
       Potentially Harmful Applications</a>. Verify Apps is enabled by default
       on devices with <a href="http://www.android.com/gms">Google Mobile Services</a>,
       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.
  <li> As appropriate, Google Hangouts and Messenger applications do not automatically
       pass media to processes such as Mediaserver.
</ul>

<h2 id=security_vulnerability_details>Security Vulnerability Details</h2>


<p>In the sections below, we provide details for each of the security
vulnerabilities listed in the <a href="#security_vulnerability_summary">
Security Vulnerability Summary</a> above. There is a description of the issue,
a severity rationale, and a table with the CVE, associated Android 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.</p>

<h3 id=remote_code_execution_vulnerability_in_mediaserver>
Remote Code Execution Vulnerability in Mediaserver</h3>


<p>A remote code execution vulnerability in Mediaserver could enable an attacker
using a specially crafted file to cause memory corruption during media file and
data processing. This issue is rated as Critical due to the possibility of
remote code execution within the context of the Mediaserver process. The
Mediaserver process has access to audio and video streams, as well as access to
privileges that third-party apps could not normally access.</p>

<p>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.</p>

Elevation of Privilege Vulnerability in Mediaserver</h3>


<p>An elevation of privilege vulnerability in Mediaserver could enable a local
malicious application to execute arbitrary code within the context of an
elevated system application. This issue is rated as High because it could be

<h2 id=common_questions_and_answers>Common Questions and Answers</h2>


<p>This section answers common questions that may occur after reading this
bulletin.</p>

<p><strong>1. How do I determine if my device is updated to address these issues?</strong></p>

<p>Security Patch Levels of June 01, 2016 or later address these issues (refer to
the <a href="https://support.google.com/nexus/answer/4457705">Nexus documentation</a>
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]:[2016-06-01]</p>

<p id="nexus_devices"><strong>2. How do I determine which Nexus devices are affected by each issue?</strong></p>

<p>In the <a href="#security_vulnerability_summary">Security Vulnerability Details</a> 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:</p>

<ul>
  <li> <strong>All Nexus devices</strong>: If an issue affects all Nexus devices, the table
       will have “All Nexus” in the <em>Updated Nexus devices</em> column. “All Nexus”
       encapsulates the following <a href="https://support.google.com/nexus/answer/4457705#nexus_devices">
       supported devices</a>: Nexus 5, Nexus 5X, Nexus 6, Nexus 6P, Nexus 7 (2013),
       Nexus 9, Android One, Nexus Player, and Pixel C.</li>
  <li> <strong>Some Nexus devices</strong>: If an issue doesn’t affect all Nexus devices,
       the affected Nexus devices are listed in the <em>Updated Nexus devices</em> column.</li>
  <li> <strong>No Nexus devices</strong>: If no Nexus devices are affected by the issue,
       the table will have “None” in the <em>Updated Nexus devices</em> column.</li>
</ul>
