We encourage all users to update to 159the latest version of Android where possible. 160 <li> The Android Security team is actively monitoring for abuse with Verify Apps and 161SafetyNet which will warn about potentially harmful applications about to be 162installed. Device rooting tools are prohibited within Google Play. To protect 163users who install applications from outside of Google Play, Verify Apps is 164enabled by default and will warn users about known rooting applications. Verify 165Apps attempts to identify and block installation of known malicious 166applications that exploit a privilege escalation vulnerability. If such an 167application has already been installed, Verify Apps will notify the user and 168attempt to remove any such applications. 169 <li> As appropriate, Google has updated the Hangouts and Messenger applications so 170that media is not automatically passed to vulnerable processes (such as 171mediaserver.) 172</ul> 173 174<h2 id=acknowledgements>Acknowledgements</h2> 175 176 177<p>We would like to thank these researchers for their contributions:</p> 178 179<ul> 180 <li> Brennan Lautner: CVE-2015-3863 181 <li> Chiachih Wu and Xuxian Jiang of C0RE Team from Qihoo 360: CVE-2015-3868, CVE-2015-3869, CVE-2015-3862 182 <li> Yajin Zhou, Lei Wu, and Xuxian Jiang of C0RE Team from Qihoo 360: CVE-2015-3865 183 <li> Daniel Micay (daniel.micay@copperhead.co) at Copperhead Security: CVE-2015-3875 184 <li> dragonltx of Alibaba Mobile Security Team: CVE-2015-6599 185 <li> Ian Beer and Steven Vittitoe of Google Project Zero: CVE-2015-6604 186 <li> Joaquín Rinaudo (@xeroxnir) and Iván Arce (@4Dgifts) of Programa STIC at 187Fundación Dr. Manuel Sadosky, Buenos Aires Argentina: CVE-2015-3870 188 <li> Josh Drake of Zimperium: CVE-2015-3876, CVE-2015-6602 189 <li> Jordan Gruskovnjak of Exodus Intelligence (@jgrusko): CVE-2015-3867 190 <li> Peter Pi of Trend Micro: CVE-2015-3872, CVE-2015-3871 191 <li> Ping Li of Qihoo 360 Technology Co.
