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 Google Developer site. Security Patch Levels of April 02, 2016 or later address these issues (refer to the Nexus documentation for instructions on how to check the security patch level).
Partners were notified about the issues described in the bulletin on March 16, 2016 or earlier. Where applicable, source code patches for these issues have been released to the Android Open Source Project (AOSP) repository.
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 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.
Android Security Advisory 2016-03-18 previously discussed use of CVE-2015-1805 by a rooting application. CVE-2015-1805 is resolved in this update. There have been no reports of active customer exploitation or abuse of the other newly reported issues. Refer to the Mitigations section for further details on the Android security platform protections and service protections such as SafetyNet, which improve the security of the Android platform.
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.
The Android Security team would like to thank these researchers for their contributions:
The Android Security team also thanks Yuan-Tsung Lo, Wenke Dou, Chiachih Wu (@chiachih_wu), and Xuxian Jiang of C0RE Team and Zimperium for their contribution to CVE-2015-1805.
The sections below contain details for each of the security vulnerabilities that apply to the 2016-04-02 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. When available, we will link the AOSP commit 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.
A vulnerability in the Dynamic Host Configuration Protocol service could enable an attacker to cause memory corruption, which could lead to remote code execution. This issue is rated as Critical severity due to the possibility of remote code execution within the context of the DHCP client.
