Multiple Vulnerabilities in Adobe Reader and Adobe Acrobat Could Allow Remote Code Execution (APSB14-28)

ITS Advisory Number: 
2014-113
Date(s) Issued: 
Tuesday, December 9, 2014
Subject: 
Multiple Vulnerabilities in Adobe Reader and Adobe Acrobat Could Allow Remote Code Execution (APSB14-28)
Overview: 

Multiple vulnerabilities have been discovered in Adobe Reader and Adobe Acrobat. Adobe Reader and Acrobat are applications for handling PDF files.

Attackers can exploit these issues to execute arbitrary code within the context of the affected application. Successful exploitation of these vulnerabilities could result in an attacker gaining the same privileges as the user running the affected application. 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. Failed exploit attempts will likely cause denial-of-service conditions.

Systems Affected: 
  • Adobe Reader XI (11.0.09) and earlier 11.x versions
  • Adobe Reader X (10.1.12) and earlier 10.x versions
  • Adobe Acrobat XI (11.0.09) and earlier 11.x versions
  • Adobe Acrobat X (10.1.12) and earlier 10.x versions

Description: 

Multiple vulnerabilities have been discovered in Adobe Reader and Adobe Acrobat that could allow an attacker to take over the affected system. Adobe recommends users update their product installations to the latest versions.

These updates resolve:

  • A use-after-free vulnerabilities that could lead to code execution (CVE-2014-8454, CVE-2014-8455, CVE-2014-9165)
  • A heap-based buffer overflow vulnerabilities that could lead to code execution (CVE-2014-8457, CVE-2014-8460, CVE-2014-9159)
  • An integer overflow vulnerability that could lead to code execution (CVE-2014-8449)
  • A memory corruption vulnerabilities that could lead to code execution (CVE-2014-8445, CVE-2014-8446, CVE-2014-8447, CVE-2014-8456, CVE-2014-8458, CVE-2014-8459, CVE-2014-8461, CVE-2014-9158)
  • A time-of-check time-of-use (TOCTOU) race condition that could be exploited to allow arbitrary write access to the file system (CVE-2014-9150)
  • An improper implementation of a Javascript API that could lead to information disclosure (CVE-2014-8448, CVE-2014-8451)
  • A vulnerability in the handling of XML external entities that could lead to information disclosure (CVE-2014-8452)
  • A vulnerabilities that could be exploited to circumvent the same-origin policy (CVE-2014-8453)

Successful exploitation of these vulnerabilities could result in an attacker gaining the same privileges as the user running the affected application. 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:

  • Apply appropriate patch provided by Microsoft to vulnerable systems immediately after appropriate testing.
  • Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources.
  • Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
  • Remind users not to open email attachments from unknown users or suspicious emails from trusted sources.
