Refer to the <a href="#common_questions_and_answers">Common Questions and Answers</a> section for more details.</p> 34 35 <p>Partners were notified about and provided updates for these issues on November 36 2, 2015 or earlier. Where applicable, source code patches for these issues have been released to 37 the Android Open Source Project (AOSP) repository.</p> 38 39 <p>The most severe of these issues is a Critical security vulnerability that could 40 enable remote code execution on an affected device through multiple methods 41 such as email, web browsing, and MMS when processing media files. The 42 <a href="/security/overview/updates-resources.html#severity">severity 43 assessment</a> is based on the effect that exploiting the vulnerability would 44 possibly have on an affected device, assuming the platform and service 45 mitigations are disabled for development purposes or if successfully bypassed.</p> 46 47 <p>We have had no reports of active customer exploitation of these newly reported 48 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 49 Android platform. We encourage all customers to accept these updates to their 50 devices.</p> 51 52 53 <h2 id="mitigations">Mitigations</h2> 54 55 56 <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 57 likelihood that security vulnerabilities could be successfully exploited on 58 Android.</p> 59 60 <ul> 61 <li> Exploitation for many issues on Android is made more difficult by enhancements 62 in newer versions of the Android platform. We encourage all users to update to 63 the latest version of Android where possible.</li> 64 <li> The Android Security team is actively monitoring for abuse with Verify Apps and 65 SafetyNet which will warn about potentially harmful applications about to be 66 installed. Device rooting tools are prohibited within Google Play. To protect 67 users who install applications from outside of Google Play, Verify Apps is 68 enabled by default and will warn users about known rooting applications. Verify 69 Apps attempts to identify and block installation of known malicious 70 applications that exploit a privilege escalation vulnerability. If such an 71 application has already been installed, Verify Apps will notify the user and 72 attempt to remove any such applications.</li> 73 <li> As appropriate, Google Hangouts and Messenger applications do not automatically 74 pass media to processes such as mediaserver.</li> 75 </ul> 76 77 <h2 id="acknowledgements">Acknowledgements</h2> 78 79 <p>We would like to thank these researchers for their contributions:</p> 80 81 <ul> 82 <li> Abhishek Arya, Oliver Chang, and Martin Barbella of Google Chrome Security 83 Team: CVE-2015-6616, CVE-2015-6617, CVE-2015-6623, CVE-2015-6626, 84 CVE-2015-6619, CVE-2015-6633, CVE-2015-6634 85 <li> Flanker (<a href="https://twitter.com/flanker_hqd">@flanker_hqd</a>) of <a href="http://k33nteam.org/">KeenTeam</a> (<a href="https://twitter.com/k33nteam">@K33nTeam</a>): CVE-2015-6620 86 <li> Guang Gong () (<a href="https://twitter.com/oldfresher">@oldfresher</a>, higongguang (a] gmail.com) of <a href="http://www.360.cn">Qihoo 360 Technology Co.Ltd</a>: CVE-2015-6626 87 <li> Mark Carter (<a href="https://twitter.com/hanpingchinese">@hanpingchinese</a>) of EmberMitre Ltd: CVE-2015-6630 88 <li> Micha Bednarski (<a href="https://github.com/michalbednarski">https://github.com/michalbednarski</a>): CVE-2015-6621 89 <li> Natalie Silvanovich of Google Project Zero: CVE-2015-6616 90 <li> Peter Pi of Trend Micro: CVE-2015-6616, CVE-2015-6628 91 <li> Qidan He (<a href="https://twitter.com/flanker_hqd">@flanker_hqd</a>) and Marco Grassi (<a href="https://twitter.com/marcograss">@marcograss</a>) of <a href="http://k33nteam.org/">KeenTeam</a> (<a href="https://twitter.com/k33nteam">@K33nTeam</a>): CVE-2015-6622 92 <li> Tzu-Yin (Nina) Tai: CVE-2015-6627 93 <li> Joaqun Rinaudo (<a href="https://twitter.com/xeroxnir">@xeroxnir</a>) of Programa 94 STIC at Fundacin Dr. Manuel Sadosky, Buenos Aires, Argentina: CVE-2015-6631 95 <li>Wangtao (neobyte) of Baidu X-Team: CVE-2015-6626 96 </ul> 97 98 <h2 id="security_vulnerability_details">Security Vulnerability Details</h2> 99 100 <p>In the sections below, we provide details for each of the security 101 vulnerabilities that apply to the 2015-12-01 patch level. 102 There is a description of the issue, a severity rationale, and a table 103 with the CVE, associated bug, severity, updated versions, and date reported. 104 When available, we will link the AOSP change that addressed the issue to the 105 bug ID.
