Android Security BulletinFebruary 2017
Published February 06, 2017 | Updated February 8, 2017
The Android Security Bulletin contains details of security vulnerabilities
affecting Android devices. Alongside the bulletin, we have released a security
update to Google devices through an over-the-air (OTA) update. The Google
device firmware images have also been released to the Google Developer site.
Security patch levels of February 05, 2017 or later address all of these
issues. Refer to the Pixel and Nexus update schedule to learn how to check a
device's security patch level.
Partners were notified of the issues described in the bulletin on January 03,
2017 or earlier. 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.
The most severe of these issues is a Critical security vulnerability that
could enable remote code execution on an affected device through multiple
methods such as email, web browsing, and MMS when processing media files.
We have had no reports of active customer exploitation or abuse of these newly
reported issues. Refer to the Android and Google service mitigations section
for details on the Android security platform protections and service
protections such as SafetyNet, which improve the security of the Android
platform.
We encourage all customers to accept these updates to their devices.
Announcements
This bulletin has two security patch level strings to provide Android
partners with the flexibility to more quickly fix a subset of vulnerabilities
that are similar across all Android devices. See Common questions and answers
for additional information: 2017-02-01: Partial security patch level string.
This security patch level string indicates that all issues associated with
2017-02-01 (and all previous security patch level strings) are addressed.
2017-02-05: Complete security patch level string. This security patch level
string indicates that all issues associated with 2017-02-01 and 2017-02-05
(and all previous security patch level strings) are addressed. Supported
Google devices will receive a single OTA update with the February 05, 2017
security patch level.
Security vulnerability summary
The tables below contains a list of security vulnerabilities, the Common
Vulnerability and Exposures ID (CVE), the assessed severity, and whether or
not Google devices are affected. The severity assessment is based on the
effect that exploiting the vulnerability would possibly have on an affected
device, assuming the platform and service mitigations are disabled for
development purposes or if successfully bypassed. 2017-02-01 security patch

* Supported Google devices on Android 7.0 or later that have installed all
available updates are not affected by this vulnerability. Android and Google
service mitigations
This is a summary of the mitigations provided by the Android security platform
and service protections, such as SafetyNet. These capabilities reduce the
likelihood that security vulnerabilities could be successfully exploited on
Android.
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. The Android
Security team actively monitors for abuse with Verify Apps and SafetyNet,
which are designed to warn users about Potentially Harmful Applications.
Verify Apps is enabled by default on devices with Google Mobile Services and
is especially important for users who install applications from outside of
Google Play. Device rooting tools are prohibited within Google Play, but
Verify Apps warns users when they attempt to install a detected rooting
applicationno matter where it comes from. Additionally, Verify Apps attempts
to identify and block installation of known malicious applications that
exploit a privilege escalation vulnerability. If such an application has
already been installed, Verify Apps will notify the user and attempt to remove
the detected application. As appropriate, Google Hangouts and Messenger
applications do not automatically pass media to processes such as Mediaserver.

Common Questions and Answers
This section answers common questions that may occur after reading this
bulletin.
1. How do I determine if my device is updated to address these issues?
To learn how to check a device's security patch level, read the instructions
on the Pixel and Nexus update schedule.
Security patch levels of 2017-02-01 or later address all issues associated
with the 2017-02-01 security patch level. Security patch levels of 2017-02-05
or later address all issues associated with the 2017-02-05 security patch
level and all previous patch levels.
Device manufacturers that include these updates should set the patch string
level to:
[ro.build.version.security_patch]:[2017-02-01]
[ro.build.version.security_patch]:[2017-02-05]
2. Why does this bulletin have two security patch levels?
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.
Devices that use the January 1, 2017 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. Devices that use the security
patch level of January 5, 2017 or newer must include all applicable patches in
this (and previous) security bulletins.
Partners are encouraged to bundle the fixes for all issues they are addressing
in a single update.
3. How do I determine which Google devices are affected by each issue?
In the 2017-02-01 and 2017-02-05 security vulnerability details sections, each
table has an Updated Google devices column that covers the range of affected
Google devices updated for each issue. This column has a few options:
All Google devices: If an issue affects All and Pixel devices, the table
will have "All" in the Updated Google devices column. "All" encapsulates the
following supported devices: Nexus 5X, Nexus 6, Nexus 6P, Nexus 7 (2013),
Nexus 9, Android One, Nexus Player, Pixel C, Pixel, and Pixel XL. Some Google
devices: If an issue doesn't affect all Google devices, the affected Google
devices are listed in the Updated Google devices column. No Google devices: If
no Google devices running Android 7.0 are affected by the issue, the table
will have "None" in the Updated Google devices column.
4. What do the entries in the references column map to?
Entries under the References column of the vulnerability details table may
contain a prefix identifying the organization to which the reference value
belongs. These prefixes map as follows: Prefix Reference
A- Android bug ID
QC- Qualcomm reference number
M- MediaTek reference number
N- NVIDIA reference number
B- Broadcom reference number Revisions
