 <p><em>Published October 1, 2018 | Updated October 1, 2018</em></p>

 <p>
 The Android Security Bulletin contains details of security vulnerabilities
 affecting Android devices. Security patch levels of 2018-10-05 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"
    class="external">Check and 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 security vulnerability in
 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/">Android security platform protections</a>
 and Google Play Protect, which improve the security of the Android platform.
 </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/2018-10-01">October 2018
 Pixel&hairsp;/&hairsp;Nexus Security Bulletin</a>.
 </p>

 <h2 id="mitigations">Android and Google service mitigations</h2>
 <p>
 This is a summary of the mitigations provided by the
 <a href="/security/enhancements/">Android security platform</a>
 and service protections such as
 <a href="https://www.android.com/play-protect" class="external">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" class="external">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" class="external">Google Mobile
 Services</a>, and is especially important for users who install apps from
 outside of Google Play.</li>
 </ul>
 <h2 id="2018-10-01-details">2018-10-01 security patch level vulnerability details</h2>
 <p>
 In the sections below, we provide details for each of the security
 vulnerabilities that apply to the 2018-10-01 patch level. Vulnerabilities are
 grouped under the component 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, such as 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>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"
    class="external">Check and update your Android version</a>.</p>
 <ul>
 <li>Security patch levels of 2018-10-01 or later address all issues associated
 with the 2018-10-01 security patch level.</li>
 <li>Security patch levels of 2018-10-05 or later address all issues associated
 with the 2018-10-05 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]:[2018-10-01]</li>
  <li>[ro.build.version.security_patch]:[2018-10-05]</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 2018-10-01 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 2018-10-05 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.

 <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 to declare the latest security patch level on Android
 devices. Additional security vulnerabilities that are documented in the
 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"
    class="external">Samsung</a>,
 <a href="https://lgsecurity.lge.com/security_updates.html"
    class="external">LGE</a>, or
 <a href="/security/bulletin/pixel/"
    class="external">Pixel&hairsp;/&hairsp;Nexus</a> security bulletins.

	<p>
	The Android Security Bulletin contains details of security vulnerabilities
	affecting Android devices. Security patch levels of 2018-10-05 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"
	class="external">Check and 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 security vulnerability in
	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/">Android security platform protections</a>
	and Google Play Protect, which improve the security of the Android platform.
	</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/2018-10-01">October 2018
	Pixel&hairsp;/&hairsp;Nexus Security Bulletin</a>.
	</p>

	<h2 id="mitigations">Android and Google service mitigations</h2>
	<p>
	This is a summary of the mitigations provided by the
	<a href="/security/enhancements/">Android security platform</a>
	and service protections such as
	<a href="https://www.android.com/play-protect" class="external">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" class="external">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" class="external">Google Mobile
	Services</a>, and is especially important for users who install apps from
	outside of Google Play.</li>
	</ul>
	<h2 id="2018-10-01-details">2018-10-01 security patch level vulnerability details</h2>
	<p>
	In the sections below, we provide details for each of the security
	vulnerabilities that apply to the 2018-10-01 patch level. Vulnerabilities are
	grouped under the component 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, such as the AOSP change list. When
	multiple changes relate to a single bug, additional references are linked to
	numbers following the bug ID.

	</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 2018-10-01 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 2018-10-05 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.

	<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 Pixel&hairsp;/&hairsp;Nexus devices
	available from the
	<a href="https://developers.google.com/android/drivers" class="external">Google
	Developer site</a>.

	<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 to declare the latest security patch level on Android
	devices. Additional security vulnerabilities that are documented in the
	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"
	class="external">Samsung</a>,
	<a href="https://lgsecurity.lge.com/security_updates.html"
	class="external">LGE</a>, or
	<a href="/security/bulletin/pixel/"
	class="external">Pixel&hairsp;/&hairsp;Nexus</a> security bulletins.
