<p><em>Published April 2, 2018 | Updated April 10, 2018</em></p>
<p>
The Pixel&hairsp;/&hairsp;Nexus Security Bulletin contains details of security
vulnerabilities and functional improvements affecting
<a href="https://support.google.com/pixelphone/answer/4457705#pixel_phones&nexus_devices">supported
Google Pixel and Nexus devices</a> (Google devices). For Google devices,
security patch levels of 2018-04-05 or later address all issues in this
bulletin and all issues in the <a href="/security/bulletin/2018-04-01">April
2018 Android Security Bulletin</a>. To learn how to check a device's security
patch level, see <a href="https://support.google.com/pixelphone/answer/4457705">Check
and update your Android version</a>.</p>
<p>
All supported Google devices will receive an update to the 2018-04-05 patch
level. We encourage all customers to accept these updates to their devices.
</p>
<p class="note">
<strong>Note:</strong> The Google device firmware images are available on the
<a href="https://developers.google.com/android/nexus/images">Google Developer
site</a>.
</p>
<h2 id="announcements">Announcements</h2>
<p>In addition to the security vulnerabilities described in the
<a href="/security/bulletin/2018-04-01">April 2018 Android Security Bulletin</a>,
Google devices also contain patches for the security vulnerabilities
described below. Partners were notified of these issues at least a month ago
and may choose to incorporate them as part of their device updates.</p>
<h2 id="security-patches">Security patches</h2>
<p>
Vulnerabilities are grouped under the component that they affect. There is a
description of the issue and a table with the CVE, associated references,
<a href="#type">type of vulnerability</a>,
<a href="https://source.android.com/security/overview/updates-resources.html#severity">severity</a>,
and updated Android Open Source Project (AOSP) versions (where applicable). When
available, we 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.

<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 2018-04-05 or later address all issues associated with
the 2018-04-05 security patch level and all previous patch levels. 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>
<p id="type">
<strong>2. What do the entries in the <em>Type</em> column mean?</strong>
</p>
<p>
Entries in the <em>Type</em> column of the vulnerability details table reference
the classification of the security vulnerability.
</p>
<table>
<col width="25%">
<col width="75%">
<tr>
<th>Abbreviation</th>

</tr>
<tr>
<td>RCE</td>
<td>Remote code execution</td>

<strong>3. What do the entries in the <em>References</em> column mean?</strong>
</p>
<p>
Entries under the <em>References</em> column of the vulnerability details table
may contain a prefix identifying the organization to which the reference value
belongs.
</p>
<table>
<col width="25%">
<col width="75%">

<th>Prefix</th>
<th>Reference</th>

<tr>
<td>A-</td>
<td>Android bug ID</td>

</table>
<p id="asterisk">
<strong>4. What does a * next to the Android bug ID in the <em>References</em>
column mean?</strong>
</p>
<p>
Issues that are not publicly available have a * next to the Android bug ID in
the <em>References</em> column. The update for that issue is generally contained
in the latest binary drivers for Nexus devices available from the
<a href="https://developers.google.com/android/nexus/drivers">Google Developer
site</a>.
</p>
<p>
<strong>5. Why are security vulnerabilities split between this bulletin and the
Android Security Bulletins?</strong>
</p>
<p>
Security vulnerabilities that are documented in the Android Security Bulletins
are required in order to declare the latest security patch level on Android
devices. Additional security vulnerabilities, such as those documented in this
bulletin, are not required for declaring a security patch level.
