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

ITS Advisory Number: 
2021-060
Date(s) Issued: 
Tuesday, May 4, 2021
Subject: 
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. Successful exploitation of the most severe of these vulnerabilities could allow for remote 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.

 

THREAT INTELLIGENCE:

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

Systems Affected: 
  • Android OS builds utilizing Security Patch Levels issued prior to May 5, 2021.

  • A vulnerability in Media Framework that could allow for Escalation of Privilege (CVE-2021-0482)
  • A vulnerability in Media Framework that could allow for Information Disclosure (CVE-2021-0484)
  • Multiple vulnerabilities in System that could allow for Remote Code Execution (CVE-2021-0473, CVE-2021-0474, CVE-2021-0475)
  • Multiple vulnerabilities in System that could allow for Escalation of Privilege (CVE-2021-0476,  CVE-2021-0477, CVE-2021-0481)
  • Multiple vulnerabilities in System that could allow for Information Disclosure (CVE-2021-0466, CVE-2021-0480)
  • A vulnerability in Kernel Components that could allow for Escalation of Privilege (CVE-2020-29661)
  • A Critical severity vulnerability in AMLogic components (CVE-2021-0467)
  • Multiple High severity vulnerabilities in ARM components (CVE-2021-28663, CVE-2021-28664)
  • Multiple High severity vulnerabilities in MediaTek components (CVE-2021-0489, CVE-2021-0490, CVE-2021-0491, CVE-2021-0492, CVE-2021-0493, CVE-2021-0494, CVE-2021-0495, CVE-2021-0496, CVE-2021-0497, CVE-2021-0498)
  • A High severity vulnerability in Unisoc components (CVE-2021-0324)
  • Multiple High severity vulnerabilities in Qualcomm components (CVE-2021-1891, CVE-2021-1905, CVE-2021-1927)
  • A Moderate severity vulnerability in Qualcomm components (CVE-2021-1906)
  • Multiple High severity vulnerabilities in Qualcomm closed-source components (CVE-2020-11273, CVE-2020-11274, CVE-2020-11279, CVE-2020-11284, CVE-2020-11285, CVE-2020-11288, CVE-2020-11289, CVE-2021-1910, CVE-2021-1915)

 

Successful exploitation of the most severe of these vulnerabilities could allow for remote 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.

Actions: 
  • After appropriate testing, immediately apply updates 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.
