<p><em>Published February 06, 2017 | Updated February 8, 2017</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 Google devices through an over-the-air (OTA) update. The Google device
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 February 05, 2017 or later address all of
these issues. Refer to the <a
href="https://support.google.com/pixelphone/answer/4457705#pixel_phones&nexus_devices">Pixel
and Nexus update schedule</a> to learn how to check a device's security patch
level.
</p>
<p>
Partners were notified of the issues described in the bulletin on January 03,
2017 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.
</p>
<p>
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
<a href="/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 if successfully bypassed.
</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="/security/enhancements/index.html">Android
security platform protections</a> and service protections such as <a
href="https://developer.android.com/training/safetynet/index.html">SafetyNet</a>,
which improve the security of the Android platform.
</p>
<p>
We encourage all customers to accept these updates to their devices.
</p>
<h2 id="announcements">Announcements</h2>
<ul>
<li>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 <a
href="#common-questions-and-answers">Common questions and answers</a> for
additional information:
<ul>
<li><strong>2017-02-01</strong>: Partial security patch level string. This
security patch level string indicates that all issues associated with 2017-02-01
(and all previous security patch level strings) are addressed.</li>
<li><strong>2017-02-05</strong>: Complete security patch level string. This
security patch level string indicates that all issues associated with 2017-02-01
and 2017-02-05 (and all previous security patch level strings) are addressed.</li>
</ul>
</li>
<li>Supported Google devices will receive a single OTA update with the February
05, 2017 security patch level.</li>
</ul>
<h2 id="mitigations">Android and Google service mitigations</h2>
<p>This is a summary of the mitigations provided by the <a
href="/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>
<li>The Android Security team actively monitors for abuse with
<a href="http://static.googleusercontent.com/media/source.android.com/en//security/reports/Google_Android_Security_2015_Report_Final.pdf">
Verify Apps and SafetyNet</a>, which are designed to warn users about
<a href="http://static.googleusercontent.com/media/source.android.com/en//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>
<li>As appropriate, Google Hangouts and Messenger applications do not
automatically pass media to processes such as Mediaserver.</li>

vulnerabilities that apply to the 2017-02-01 patch level. There is a description
of the issue, a severity rationale, and a table with the CVE, associated
references, severity, updated Google devices, updated AOSP versions (where
applicable), and date reported. When available, we will link the public change
that addressed the issue to the bug ID, like the AOSP change list. When multiple
changes relate to a single bug, additional references are linked to numbers
following the bug ID.</p>
<h3 id="rce-in-surfaceflinger">Remote code execution vulnerability in
Surfaceflinger</h3>
<p>
A remote code execution vulnerability in Surfaceflinger 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 Surfaceflinger
process.

<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>To learn how to check a device's security patch level, read the instructions on
the <a href="https://support.google.com/pixelphone/answer/4457705#pixel_phones&nexus_devices">
Pixel and Nexus update schedule</a>.</p>
<ul>
<li>Security patch levels of 2017-02-01 or later address all issues associated
with the 2017-02-01 security patch level.</li>
<li>Security patch levels of 2017-02-05 or later address all issues associated
with the 2017-02-05 security patch level and all previous patch levels.
</li>
</ul>
<p>Device manufacturers that include these updates should set the patch string
level to:</p>
<ul>
<li><code>[ro.build.version.security_patch]:[2017-02-01]</code></li>
<li><code>[ro.build.version.security_patch]:[2017-02-05]</code></li>
</ul>
<p><strong>2. Why does this bulletin have two security patch levels?</strong></p>
<p>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.</p>
<ul>
<li>Devices that use the February 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.</li>
<li>Devices that use the security patch level of February 5, 2017 or newer must
include all applicable patches in this (and previous) security
bulletins.</li>
</ul>
<p>Partners are encouraged to bundle the fixes for all issues they are addressing
in a single update.</p>
<p><strong>3. How do I determine which Google devices are affected by each
issue?</strong></p>
<p>In the <a href="#2017-02-01-details">2017-02-01</a> and
<a href="#2017-02-05-details">2017-02-05</a>
security vulnerability details sections, each table has an <em>Updated Google
devices</em> column that covers the range of affected Google devices updated for
each issue. This column has a few options:
</p>
<ul>
<li><strong>All Google devices</strong>: If an issue affects All and Pixel
devices, the table will have "All" in the <em>Updated Google devices</em>
column. "All" encapsulates the following <a
href="https://support.google.com/pixelphone/answer/4457705#pixel_phones&nexus_devices">supported
devices</a>: Nexus 5X, Nexus 6, Nexus 6P, Nexus 9, Android One,
Nexus Player, Pixel C, Pixel, and Pixel XL.</li>
<li><strong>Some Google devices</strong>: If an issue doesn't affect all Google
devices, the affected Google devices are listed in the <em>Updated Google
devices</em> column.</li>
