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

OVERVIEW

Multiple vulnerabilities have been discovered in the Google Android operating system (OS), the most severe of which could allow for remote code execution. Android is an operating system developed by Google for mobile devices, including, but not limited to, smartphones, tablets, and watches. These vulnerabilities could be exploited through multiple methods such as email, web browsing, and MMS when processing media files. Successful exploitation of the most severe of these vulnerabilities could result in remote code execution in the context of the application. 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.

THREAT INTELLIGENCE

There are currently no reports of these vulnerabilities being exploited in the wild.

SYSTEMS AFFECTED

Android OS builds utilizing Security Patch Levels prior to February 01, 2017.

RECOMMENDATIONS

We recommend the following actions be taken:

• Apply appropriate updates provided by Google Android or mobile carriers to vulnerable systems, immediately after appropriate testing.

• Run all software as a non-privileged user to diminish the effects of a successful attack.

• Remind users to download apps only 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 the threats posed by hypertext links contained in emails or attachments especially from un-trusted sources.
