ITS Advisory Number: 
2013-093
Date(s) Issued: 
Tuesday, October 8, 2013
Subject: 
Vulnerability in Adobe Reader and Acrobat Could Allow For Remote Code Execution (APSB13-25)
Overview: 

A vulnerability has been discovered in Adobe Reader and Adobe Acrobat that could allow an attacker to take control of the affected system.  Adobe Reader is used for viewing, printing, signing and commenting on PDF documents and 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 then install programs; view, change, or delete data; or create new accounts with full user rights. Failed exploit attempts will likely cause denial-of-service conditions.

Systems Affected: 
  • Adobe Reader XI (11.0.04) for Windows
  • Adobe Acrobat XI (11.0.04) for Windows

Description: 

A vulnerability has been discovered in Adobe Reader and Adobe Acrobat that could allow an attacker to take control of the affected system.  This vulnerability is caused by a regression that occurred in version 11.0.04 affecting Javascript security controls. The attacker can take control of the affected system by launching JavaScript scheme URIs while viewing a PDF in a browser (CVE-2013-5325). Adobe Reader and Acrobat X (10.1.8) and earlier versions for Windows are not affected, and all versions of Adobe Reader and Acrobat for Macintosh are also not affected by this vulnerability. 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 then install programs; view, change, or delete data; or create new accounts with full user rights. Failed exploit attempts will likely cause denial-of-service conditions.

Actions: 
  • 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.
