Vulnerabilities in Adobe Acrobat and Adobe Reader Could Allow Arbitrary Code

ITS Advisory Number: 
2016-140
Date(s) Issued: 
Friday, August 26, 2016
Subject: 
Vulnerabilities in Adobe Acrobat and Adobe Reader Could Allow Arbitrary Code
Overview: 

Multiple vulnerabilities in Adobe Acrobat and Adobe Reader could allow for arbitrary code execution. Adobe Acrobat and Reader allow a user to view, create, manipulate, print and manage files in Portable Document Format (PDF). Successful exploitation could potentially allow an attacker to take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full system rights.

Systems Affected: 

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

Description: 

Adobe Acrobat and Reader are prone to multiple vulnerabilities, the most severe of which could allow for arbitrary code execution. The vulnerabilities are as follows:

 

  • Integer overflow vulnerability that could lead to code execution (CVE-2016-4210).

  • Use-after-free vulnerability that could lead to code execution (CVE-2016-4255).

  • Heap buffer overflow vulnerability that could lead to code execution (CVE-2016-4209).

  • Bypass restrictions on JavaScript API execution (CVE-2016-4215).

  • Memory corruption vulnerabilities that could lead to code execution (CVE-2016-4254, CVE-2016-4191, CVE-2016-4192, CVE-2016-4193, CVE-2016-4194, CVE-2016-4195, CVE-2016-4196, CVE-2016-4197, CVE-2016-4198, CVE-2016-4199, CVE-2016-4200, CVE-2016-4201, CVE-2016-4202, CVE-2016-4203, CVE-2016-4204, CVE-2016-4205, CVE-2016-4206, CVE-2016-4207, CVE-2016-4208, CVE-2016-4211, CVE-2016-4212, CVE-2016-4213, CVE-2016-4214, CVE-2016-4250, CVE-2016-4251, CVE-2016-4252, CVE-2016-4265, CVE-2016-4266, CVE-2016-4267, CVE-2016-4268, CVE-2016-4269, CVE-2016-4270).

 

The most severe of these vulnerabilities could allow an attacker to execute arbitrary code. An attacker could then install programs; view, change, or delete data; or create new accounts with full system rights.

Actions: 
  • Immediately after appropriate testing, apply patches provided by Adobe to vulnerable systems
  • 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 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.
