Multiple Vulnerabilities in Adobe Acrobat and Adobe Reader Could Allow for Code Execution (APSB17-11)

ITS Advisory Number: 
2017-036
Date(s) Issued: 
Tuesday, April 11, 2017
Subject: 
Multiple Vulnerabilities in Adobe Acrobat and Adobe Reader Could Allow for Code Execution (APSB17-11)
Overview: 

Multiple vulnerabilities have been discovered in Adobe Acrobat and Adobe Reader, the most severe of which could allow for code execution. Adobe Acrobat and Reader allow a user to view, create, manipulate, print and manage files in Portable Document Format (PDF). Successful exploitation of the most severe of these vulnerabilities could result in the attacker gaining control of the affected system.  Depending on the privileges associated with this application, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. If this application has been configured to have fewer user rights on the system, exploitation of the most severe of these vulnerabilities could have less impact than if it was configured with administrative rights.

Systems Affected: 

Continuous Track:

  • Adobe Acrobat DC versions 15.023.20070 and prior for Windows and Macintosh
  • Adobe Acrobat Reader DC versions 15.023.20070 and prior for Windows and Macintosh

Classic Track:

  • Adobe Acrobat DC versions 15.006.30280 and prior for Windows and Macintosh
  • Adobe Acrobat Reader DC versions 15.006.30280 and prior for Windows and Macintosh

Desktop Track:

  • Adobe Acrobat XI versions 11.0.19 and prior for Windows and Macintosh
  • Adobe Reader XI versions 11.0.19 and prior for Windows and Macintosh

Description: 

Multiple vulnerabilities have been discovered in Adobe Acrobat and Adobe Reader, the most severe of which could allow for code execution. The vulnerabilities are as follows:

  • Six use-after-free vulnerabilities that could lead to code execution (CVE-2017-3014, CVE-2017-3026, CVE-2017-3027, CVE-2017-3035, CVE-2017-3047, CVE-2017-3057).
  • Four heap buffer overflow vulnerabilities that could lead to code execution (CVE-2017-3042, CVE-2017-3048, CVE-2017-3049, CVE-2017-3055).
  • Twenty-one memory corruption vulnerabilities that could lead to code execution (CVE-2017-3015, CVE-2017-3017, CVE-2017-3018, CVE-2017-3019, CVE-2017-3023, CVE-2017-3024, CVE-2017-3025, CVE-2017-3028, CVE-2017-3030, CVE-2017-3036, CVE-2017-3037, CVE-2017-3038, CVE-2017-3039, CVE-2017-3040, CVE-2017-3041, CVE-2017-3044, CVE-2017-3050, CVE-2017-3051, CVE-2017-3054, CVE-2017-3056, CVE-2017-3065).
  • Two integer overflow vulnerabilities that could lead to code execution (CVE-2017-3011, CVE-2017-3034).
  • Twelve memory corruption vulnerabilities that could lead to a memory address leak (CVE-2017-3020, CVE-2017-3021, CVE-2017-3022, CVE-2017-3029, CVE-2017-3031, CVE-2017-3032, CVE-2017-3033, CVE-2017-3043, CVE-2017-3045, CVE-2017-3046, CVE-2017-3052, CVE-2017-3053).
  • Two vulnerabilities in the directory search path used to find resources that could lead to code execution (CVE-2017-3012, CVE-2017-3013).

Successful exploitation of the most severe of these vulnerabilities could result in the attacker gaining control of the affected system.  Depending on the privileges associated with this application, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. If this application has been configured to have fewer user rights on the system, exploitation of the most severe of these vulnerabilities could have less impact than if it was configured with administrative rights.

Actions: 
  • After appropriate testing, immediately install the updates provided by Adobe.
  • 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 un-trusted sources.
  • Apply the Principle of Least Privilege to all systems and services.
