Multiple Vulnerabilities in Google Chrome Could Allow for Arbitrary Code Execution

MS-ISAC ADVISORY NUMBER:

2018-025

DATE(S) ISSUED:

03/07/2018

OVERVIEW:

Multiple vulnerabilities have been discovered in Google Chrome, the most severe of which could result in arbitrary code execution. Google Chrome is a web browser used to access the Internet. These vulnerabilities can be exploited if a user visits, or is redirected to, a specially crafted web page. Successful exploitation of the most severe of these vulnerabilities could allow an attacker to execute arbitrary code in the context of the browser, obtain sensitive information, bypass security restrictions and perform unauthorized actions, or cause denial-of-service conditions.

THREAT INTELLIGENCE:

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

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:

Multiple vulnerabilities have been discovered in Google Chrome, the most severe of which could result in arbitrary code execution. These vulnerabilities can be exploited if a user visits, or is redirected to, a specially crafted web page. Details of these vulnerabilities are as follows:

  • Use after free in Flash. (CVE-2018-6058, CVE-2018-6059)
  • Incorrect permissions on shared memory. (CVE-2018-6057, CVE-2018-6063)
  • Use after free in Blink. (CVE-2018-6060)
  • Race condition in V8. (CVE-2018-6061)
  • Heap buffer overflow in Skia. (CVE-2018-6062)
  • Incorrect permissions on shared memory. (CVE-2018-6057, CVE-2018-6063)
  • Type confusion in V8. (CVE-2018-6064)
  • Integer overflow in V8. (CVE-2018-6065)
  • Same Origin Bypass via canvas. (CVE-2018-6066)
  • Buffer overflow in Skia. (CVE-2018-6067)
  • Object lifecycle issues in Chrome Custom Tab. (CVE-2018-6068)
  • Stack buffer overflow in Skia. (CVE-2018-6069)
  • CSP bypass through extensions. (CVE-2018-6070)
  • Heap bufffer overflow in Skia. (CVE-2018-6071)
  • Integer overflow in PDFium. (CVE-2018-6072)
  • Heap bufffer overflow in WebGL. (CVE-2018-6073)
  • Mark-of-the-Web bypass. (CVE-2018-6074)
  • Overly permissive cross origin downloads. (CVE-2018-6075)
  • Incorrect handling of URL fragment identifiers in Blink. (CVE-2018-6076)
  • Timing attack using SVG filters. (CVE-2018-6077)
  • URL Spoof in OmniBox. (CVE-2018-6078)
  • Information disclosure via texture data in WebGL. (CVE-2018-6079)
  • Information disclosure in IPC call. (CVE-2018-6080)
  • XSS in interstitials. (CVE-2018-6081)
  • Circumvention of port blocking. (CVE-2018-6082)
  • Incorrect processing of AppManifests. (CVE-2018-6083)

Successful exploitation of the most severe of these vulnerabilities could allow an attacker to execute arbitrary code in the context of the browser, obtain sensitive information, bypass security restrictions and perform unauthorized actions, or cause denial-of-service conditions.

RECOMENDATIONS:

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 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.
  • Apply the Principle of Least Privilege to all systems and services.
