Vulnerability in Chrome Could Allow Arbitrary Code Execution

Vulnerability in Chrome Could Allow Arbitrary Code Execution

A cybersecurity advisory was issued Tuesday, Nov. 20, 2018, regarding a security vulnerability in Google Chrome. The vulnerability could lead to arbitrary code execution.

What It Is:
Google Chrome is a web browser used to access the Internet. Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code in the context of the browser.

Depending on the privileges associated with the application, an attacker could 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.

See the original Google Security Update.

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

What It Means:
If your business or organization uses Google Chrome, you will need to apply the appropriate stable channel update after proper testing to prevent a possible security breach.

Systems Affected Include:
• Google Chrome versions prior to 70.0.3538.110

Risk:
Government:
• Large and medium government entities: High
• Small government entities: Medium
Businesses:
• Large and medium business entities: High
• Small business entities: Medium
Home users: Low

Technical Summary:
A vulnerability has been discovered in Google Chrome, which could allow for arbitrary code execution. This vulnerability is caused by a use-after-free flaw in GPU (CVE-2018-17479). Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code in the context of the browser.

What To Do:
We recommend the following actions be taken:

• Apply stable channel update provided by Google to vulnerable systems immediately after appropriate testing.
• Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
• Remind users not to visit untrusted websites or follow links provided by unknown or untrusted sources.
• Inform and educate users regarding the threats posed by hypertext links contained in emails or attachments especially from untrusted sources.
• Apply the Principle of Least Privilege to all systems and services.

Negative Consequences of Lost or Stolen Data Include:
The loss or theft of proprietary data can have severe impacts, particularly if the compromise becomes public and sensitive information is exposed. Possible impacts include:

• Temporary or permanent loss of sensitive or proprietary information.
• Disruption to regular operations.
• Financial losses incurred to restore systems and files.
• Potential harm to an organization’s reputation.
