Update Available To Address Multiple Flaws in Android OS

Update Available To Address Multiple Flaws in Android OS

An updated cybersecurity alert was issued by Google yesterday, August 7, 2019, regarding multiple vulnerabilities in Android OS. These vulnerabilities could allow an attacker to execute arbitrary code which could potentially lead to a breach.

What It Is:
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.

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 August 5, 2019.

Risk:
Government:
• Large and medium government entities: High
• Small government entities: High
