 <p><em>Published October 2, 2017 | Updated October 3, 2017</em></p>

 <p>The Android Security Bulletin contains details of security vulnerabilities
 affecting Android devices. Security patch levels of October 05, 2017 or later
 address all of these issues. To learn how to check a device's security patch
 level, see <a href="https://support.google.com/pixelphone/answer/4457705#pixel_phones&nexus_devices">
 Check &amp; update your Android version</a>.</p>

 <p>Android partners are notified of all issues at least a month before
 publication. 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 severity vulnerability in media
 framework that could enable a remote attacker using a specially crafted file to
 execute arbitrary code within the context of a privileged process. 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 turned off 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 Play Protect mitigations</a> section
 for details on the <a href="/security/enhancements/index.html">Android
 security platform protections</a> and Google Play Protect, which improve the
 security of the Android platform.</p>

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

 <p class="note"><strong>Note:</strong> Information on the latest over-the-air
 update (OTA) and firmware images for Google devices is available in the
 <a href="/security/bulletin/pixel/2017-10-01">October 2017
 Pixel&hairsp;/&hairsp;Nexus Security Bulletin</a>.</p>

 <h2 id="announcements">Announcements</h2>
 <ul>
   <li>We have launched a new monthly
   <a href="/security/bulletin/pixel">Pixel&hairsp;/&hairsp;Nexus Security
   Bulletin</a>, which contains information on additional security
   vulnerabilities and functional improvements that are addressed on Pixel and
   Nexus devices. Android device manufacturers may choose to address these
   issues on their devices. See <a href="#split">Common questions and
   answers</a> for additional information</li>
   <li>Security bulletin acknowledgements are now listed directly in the
   <a href="/security/overview/acknowledgements.html">Android Security
   Acknowledgements</a> page.</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
 <a href="https://www.android.com/play-protect">Google Play Protect</a>. 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 through <a
   href="https://www.android.com/play-protect">Google Play Protect</a> and warns
   users about <a
   href="/security/reports/Google_Android_Security_PHA_classifications.pdf">Potentially
   Harmful Applications</a>. Google Play Protect 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 apps from outside of Google
   Play.</li>
 </ul>
 <h2 id="2017-10-01-details">2017-10-01 security patch level—Vulnerability details</h2>
 <p>In the sections below, we provide details for each of the security
 vulnerabilities that apply to the 2017-10-01 patch level. 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="/security/overview/updates-resources.html#severity">severity</a>,
 and updated 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.</p>

 <h2 id="questions">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, see
 <a
 href="https://support.google.com/pixelphone/answer/4457705#pixel_phones&nexus_devices">Check
 &amp; update your Android version</a>.</p>
 <ul>
   <li>Security patch levels of 2017-10-01 or later address all issues associated
   with the 2017-10-01 security patch level.</li>
   <li>Security patch levels of 2017-10-05 or later address all issues associated
   with the 2017-10-05 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>[ro.build.version.security_patch]:[2017-10-01]</li>
   <li>[ro.build.version.security_patch]:[2017-10-05]</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 2017-10-01 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 2017-10-05 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 id="type">
 <strong>3. 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>

 <p id="asterisk"><strong>5. 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 id="split">
 <strong>6. Why are security vulnerabilities split between this bulletin and
 device&hairsp;/&hairsp;partner security bulletins, such as the
 Pixel&hairsp;/&hairsp;Nexus bulletin?</strong>
 </p>
 <p>
 Security vulnerabilities that are documented in this security bulletin are
 required in order to declare the latest security patch level on Android devices.
 Additional security vulnerabilities that are documented in
 device&hairsp;/&hairsp;partner security bulletins are not
 required for declaring a security patch level. Android device and chipset
 manufacturers are encouraged to document the presence of other fixes on their
 devices through their own security websites, such as the
 <a href="https://security.samsungmobile.com/securityUpdate.smsb">Samsung</a>,
 <a href="https://lgsecurity.lge.com/security_updates.html">LGE</a>, or
 <a href="/security/bulletin/pixel">Pixel&hairsp;/&hairsp;Nexus</a>
 security bulletins.

	<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
	<a href="https://www.android.com/play-protect">Google Play Protect</a>. 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 through <a
	href="https://www.android.com/play-protect">Google Play Protect</a> and warns
	users about <a
	href="/security/reports/Google_Android_Security_PHA_classifications.pdf">Potentially
	Harmful Applications</a>. Google Play Protect is enabled by default on devices
	with <a href="http://www.android.com/gms">Google Mobile Services</a>, and is

	<h2 id="questions">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, see
	<a
	href="https://support.google.com/pixelphone/answer/4457705#pixel_phones&nexus_devices">Check
	& update your Android version</a>.</p>
	<ul>
	<li>Security patch levels of 2017-10-01 or later address all issues associated
	with the 2017-10-01 security patch level.</li>
	<li>Security patch levels of 2017-10-05 or later address all issues associated
	with the 2017-10-05 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>[ro.build.version.security_patch]:[2017-10-01]</li>
	<li>[ro.build.version.security_patch]:[2017-10-05]</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 2017-10-01 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 2017-10-05 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 id="type">
	<strong>3. What do the entries in the <em>Type</em> column mean?</strong></p>

	<p id="asterisk"><strong>5. 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

	<strong>6. Why are security vulnerabilities split between this bulletin and
	device&hairsp;/&hairsp;partner security bulletins, such as the
	Pixel&hairsp;/&hairsp;Nexus bulletin?</strong>
	</p>
	<p>
	Security vulnerabilities that are documented in this security bulletin are
	required in order to declare the latest security patch level on Android devices.
	Additional security vulnerabilities that are documented in
	device&hairsp;/&hairsp;partner security bulletins are not
	required for declaring a security patch level. Android device and chipset
	manufacturers are encouraged to document the presence of other fixes on their
	devices through their own security websites, such as the
