Multiple Vulnerabilities in Google Android OS Could Allow for Arbitrary Code Execution

ITS Advisory Number: 
2017-097
Date(s) Issued: 
Thursday, October 5, 2017
Subject: 
Multiple Vulnerabilities in Google Android OS Could Allow for Arbitrary Code Execution
Overview: 

Multiple vulnerabilities have been discovered in the Google Android operating system (OS), the most severe of which could allow for arbitrary code execution. Android is an operating system developed by Google for mobile devices, including, but not limited to, smartphones, tablets, and watches. Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution within the context of a privileged process. Depending on the privileges associated with this application, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. If this application has been configured to have fewer user rights on the system, exploitation of the most severe of these vulnerabilities could have less impact than if it was configured with administrative rights.

Systems Affected: 
  • Android OS builds utilizing Security Patch Levels issued prior to October 5, 2017.

Description: 

Multiple vulnerabilities have been discovered in Google Android OS, the most severe of which could allow for arbitrary code execution within the context of a privileged process. Details of these vulnerabilities are as follows:

  • An elevation of privilege vulnerability in the Framework (CVE-2017-0806)
  • Three arbitrary code execution vulnerabilities in the Media Framework (CVE-2017-0809, CVE-2017-0810, CVE-2017-0811)
  • An elevation of privilege vulnerability in the Media Framework (CVE-2017-0812)
  • Two information disclosure vulnerabilities in the Media Framework (CVE-2017-0815, CVE-2017-0816)
  • An arbitrary code execution vulnerability in the System (CVE-2017-14496)
  • Two elevation of privilege vulnerabilities in Kernel components (CVE-2017-7374, CVE-2017-9075)
  • An elevation of privilege vulnerability in MediaTek components (CVE-2017-0827)
  • An arbitrary code execution vulnerability in Qualcomm components (CVE-2017-11053)
  • Two elevation of privilege vulnerabilities in Qualcomm components (CVE-2017-9714, CVE-2017-9683)

Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution in the context of a privileged process. These vulnerabilities could be exploited through multiple methods such as email, web browsing, and MMS when processing media files. Depending on the privileges associated with the application, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. If this application has been configured to have fewer user rights on the system, exploitation of the most severe of these vulnerabilities could have less impact than if it was configured with administrative rights.

Actions: 
  • After appropriate testing, immediately apply updates provided by Google Android or mobile carriers to vulnerable systems.
  • Remind users to only download applications from trusted vendors in the Play Store.
  • Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources.
  • Inform and educate users regarding threats posed by hypertext links contained in emails or attachments, especially from un-trusted sources.
