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

ITS Advisory Number: 
2021-029-UPDATED
Date(s) Issued: 
Thursday, March 4, 2021
Date Updated: 
Thursday, March 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 March 5, 2021

March 04 - UPDATED DESCRIPTION:

  • Multiple unspecified privilege-escalation vulnerabilities. (CVE-2020-0025, CVE-2021-0370, CVE-2021-0372, CVE-2021-0377, CVE-2021-0380, CVE-2021-0383, CVE-2021-0385, CVE-2021-0386, CVE-2021-0388, CVE-2021-0389, CVE-2021-0376, CVE-2021-0375, CVE-2021-0387)
  • An unspecified information-disclosure vulnerability in Pixel System component. (CVE-2021-0371)
  • Multiple unspecified information-disclosure vulnerability in Pixel Framework component. (CVE-2021-0369, CVE-2021-0381, CVE-2021-0382)
  • Multiple moderate severity vulnerabilities in Pixel Media Framework components. (CVE-2021-0368, CVE-2021-0374, CVE-2021-0378, CVE-2021-0379, CVE-2021-0384)
  • Multiple high severity vulnerabilities in Pixel Kernel components. (CVE-2021-0454, CVE-2021-0455, CVE-2021-0456, CVE-2021-0464, CVE-2021-0465, CVE-2021-0463)
  • Multiple moderate severity vulnerabilities in Pixel Kernel components. (CVE-2020-25211,CVE-2021-0457, CVE-2021-0458, CVE-2021-0461, CVE-2021-0462, CVE-2021-25211, CVE-2021-0449, CVE-2021-0450, CVE-2021-0451, CVE-2021-0452, CVE-2021-0453, CVE-2021-0459, CVE-2021-0460)
  • A moderate severity vulnerability in Qualcomm components. (CVE-2020-11230)
  • A moderate severity vulnerability in Qualcomm closed-source components. (CVE-2020-3664)

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 the 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.
