<p><em>Published October 05, 2015 | Updated April 28, 2016</em></p>

<p>We have released a security update to Nexus devices through an over-the-air
(OTA) update as part of our Android Security Bulletin Monthly Release process.
The Nexus firmware images have also been released to the <a href="https://developers.google.com/android/nexus/images">Google Developer site</a>. Builds LMY48T or later (such as LMY48W) and Android M with Security Patch
Level of October 1, 2015 or later address these issues. Refer to the <a href="https://support.google.com/nexus/answer/4457705">Nexus documentation</a> for instructions on how to check the security patch level. </p>

<p>Partners were notified about these issues on September 10, 2015 or earlier.
Source code patches for these issues have been released to the Android Open
Source Project (AOSP) repository.</p>

<p>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. 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 disabled for development purposes or if successfully bypassed.</p>

<p>We have had no reports of active customer exploitation of these newly reported
issues. Refer to the <a href="#mitigations">Mitigations</a> section for details on the <a href="/security/enhancements/index.html">Android security platform protections</a> 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. </p>


<h2 id=mitigations>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 SafetyNet. These capabilities reduce the
likelihood that security vulnerabilities can 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> The Android Security team is actively monitoring for abuse with Verify Apps and
SafetyNet which will warn about potentially harmful applications about to be
installed. Device rooting tools are prohibited within Google Play. To protect
users who install applications from outside of Google Play, Verify Apps is
enabled by default and will warn users about known rooting applications. 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 any such applications.
  <li> As appropriate, Google has updated the Hangouts and Messenger applications so
that media is not automatically passed to vulnerable processes (such as
mediaserver.)
</ul>

<h2 id=security_vulnerability_details>Security Vulnerability Details</h2>


<p>In the sections below, we provide details for each of the security
vulnerabilities that apply to the 2015-10-01 patch level.
There is a description of the issue, a severity rationale, and a table
with the CVE, associated bug, severity, affected versions, and date reported.
Where available, weve linked the AOSP change that addressed the issue to the
bug ID.  When multiple changes relate to a single bug, additional AOSP
references are linked to numbers following the bug ID.</p>

<h3 id=remote_code_execution_vulnerabilities_in_libstagefright>Remote Code Execution Vulnerabilities in libstagefright</h3>


<p>Vulnerabilities in libstagefright exist that could allow an attacker, during
media file and data processing of a specially crafted file, to cause memory
corruption and remote code execution in the mediaserver service.</p>

<p>These issues are rated as a Critical severity due to the possibility of remote
code execution as a privileged service. The affected components have access to
audio and video streams as well as access to privileges that third-party
applications cannot normally access.</p>

<h3 id=remote_code_execution_vulnerabilities_in_libutils>Remote Code Execution Vulnerabilities in libutils </h3>


<p>Vulnerabilities in libutils, a generic library, exist in audio file processing.
These vulnerabilities could allow an attacker, during processing of a specially
crafted file, to cause memory corruption and remote code execution in a service
that uses this library such as mediaserver.</p>

<p>The affected functionality is provided as an application API and there are
multiple applications that allow it to be reached with remote content, most
notably MMS and browser playback of media. This issue is rated as a Critical
severity due to the possibility of remote code execution in a privileged
service. The affected component has access to audio and video streams as well
as access to privileges that third-party apps cannot normally access.</p>

<p>A vulnerability in the Media Projection component can allow user data to be
disclosed in the form of screen snapshots. The issue is a result of the
operating system allowing overly long application names. The use of these long
names by a local malicious application may prevent a warning about screen
recording from being visible by the user. This issue is rated as Moderate
severity because it can be used to improperly gain elevated permissions.</p>
