| <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 / Nexus Security Bulletin</a>. |
| </p> |
| <h2 id="announcements">Announcements</h2> |
| <ul> |
| <li>We have launched a new |
| <a href="/security/bulletin/pixel/">Pixel / 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%"> |

| <th>Abbreviation</th> |
| <th>Definition</th> |

| <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> |

| <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> |
| <strong>6. Why are security vulnerabilities split between this bulletin and |
| device/partner security bulletins, such as the Pixel / 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 / Nexus</a> security bulletins. |
