+<p><em>Published November 6, 2017 | Updated November 8, 2017</em></p>
+<p>
+The Android Security Bulletin contains details of security vulnerabilities
+affecting Android devices. Security patch levels of 2017-11-06 or later address
+all of these issues. To learn how to check a device's security patch level, see
+<a href="//support.google.com/pixelphone/answer/4457705">Check and update
+your Android version</a>.
+</p>
+<p>
+Android partners were notified of all issues in the 2017-11-01 and 2017-11-05
+patch levels at least a month before publication. Android partners were notified
+of all issues in the 2017-11-06 patch level within the last month. 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 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 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/2017-11-01">November 2017
+Pixel&hairsp;/&hairsp;Nexus Security Bulletin</a>.
+</p>
+<h2 id="announcements">Announcements</h2>
+<ul>
+ <li>We have launched a new
+ <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 supported
+ Pixel and Nexus devices. Android device manufacturers may choose to address
+ these issues on their devices. See <a href="#questions">Common questions and
+ answers</a> for additional information.</li>
+ <li>Security patches for the KRACK vulnerabilities are provided under the
+ 2017-11-06 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 <a
+href="//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="//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="//www.android.com/gms">Google Mobile Services</a>, and is
+ especially important for users who install apps from outside of Google
+ Play.</li>

+<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="//support.google.com/pixelphone/answer/4457705#pixel_phones&nexus_devices">Check
+& update your Android version</a>.
+</p>
+<ul>
+ <li>Security patch levels of 2017-11-01 or later address all issues associated
+ with the 2017-11-01 security patch level.</li>
+ <li>Security patch levels of 2017-11-05 or later address all issues associated
+ with the 2017-11-05 security patch level and all previous patch levels.</li>
+ <li>Security patch levels of 2017-11-06 or later address all issues associated
+ with the 2017-11-06 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]:[2017-11-01]</li>
+ <li>[ro.build.version.security_patch]:[2017-11-05]</li>
+ <li>[ro.build.version.security_patch]:[2017-11-06]</li>
+</ul>
+<p>
+<strong>2. Why does this bulletin have three security patch levels?</strong>
+</p>
+<p>
+This bulletin has three 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 2017-11-01 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 2017-11-05 security patch level must include all issues
+ associated with that security patch level, the 2017-11-01 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 2017-11-06 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>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>
+<table>
+ <col width="25%">
+ <col width="75%">
+ <tr>
+ <th>Abbreviation</th>
+ <th>Definition</th>
+ </tr>
+ <tr>
+ <td>RCE</td>

+<strong>4. 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%">

+<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="//developers.google.com/android/nexus/drivers">Google Developer
+site</a>.
+</p>
+<p>
+<strong>6. Why are security vulnerabilities split between this bulletin and
+device/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 the device/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="//security.samsungmobile.com/securityUpdate.smsb">Samsung</a>, <a
+href="//lgsecurity.lge.com/security_updates.html">LGE</a>, or <a
+href="/security/bulletin/pixel/">Pixel&hairsp;/&hairsp;Nexus</a> security bulletins.
