Vulnerabilities in Adobe Reader and Acrobat Could Allow For Remote Code Execution (APSB14-20)

ITS Advisory Number: 
2014-080
Date(s) Issued: 
Thursday, September 18, 2014
Subject: 
Vulnerabilities in Adobe Reader and Acrobat Could Allow For Remote Code Execution (APSB14-20)
Overview: 

Vulnerabilities have been discovered in Adobe Reader and Adobe Acrobat which could allow an attacker to take complete control of a vulnerable system. Adobe Reader is used for viewing, printing, signing and commenting on PDF documents. Adobe Acrobat is a family of application software developed to view, create, manipulate, print and manage files in PDF format. Successful exploitation could result in an attacker gaining the same privileges as the logged on user. Depending on the privileges associated with the user, an attacker could install programs; view, change, or delete data; or create new accounts with full user rights.

Systems Affected: 
  • Adobe Reader XI (11.0.08) and earlier 11.x versions for Windows
  • Adobe Reader XI (11.0.07) and earlier 11.x versions for Macintosh
  • Adobe Reader X (10.1.11) and earlier 10.x versions for Windows
  • Adobe Reader X (10.1.10) and earlier 10.x versions for Macintosh
  • Adobe Acrobat XI (11.0.08) and earlier 11.x versions for Windows
  • Adobe Acrobat XI (11.0.07) and earlier 11.x versions for Macintosh
  • Adobe Acrobat X (10.1.11) and earlier 10.x versions for Windows
  • Adobe Acrobat X (10.1.10) and earlier 10.x versions for Macintosh

Description: 

Adobe Reader and Adobe Acrobat XI are prone to vulnerabilities that could allow an attacker remote code execution. The summary of vulnerabilities are as follows:

  • A use-after-free vulnerability that could lead to code execution (CVE-2014-0560)
  • A universal cross-site scripting (UXSS) vulnerability in Reader and Acrobat on the Macintosh platform (CVE-2014-0562)
  • A potential denial-of-service (DoS) vulnerability related to memory corruption (CVE-2014-0563)
  • A heap overflow vulnerability that could lead to code execution (CVE-2014-0561, CVE-2014-0567)
  • A memory corruption vulnerabilities that could lead to code execution (CVE-2014-0565, CVE-2014-0566)
  • A sandbox bypass vulnerability that could be exploited to run native code with escalated privileges on Windows (CVE-2014-0568)

Successful exploitation could result in an attacker gaining the same privileges as the logged on user. Depending on the privileges associated with the user, an attacker could install programs; view, change, or delete data; or create new accounts with full user rights.

Actions: 

We recommend the following actions be taken:

  • Install the updates provided by Adobe 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.
  • Remind users not to open email attachments from unknown users or suspicious emails from trusted sources.
