Multiple Vulnerabilities in Adobe Acrobat and Adobe Reader Could Allow for Remote Code Execution (APSB17-36)

MS-ISAC ADVISORY NUMBER:

2017-113

DATE(S) ISSUED:

11/14/2017

OVERVIEW:

Multiple vulnerabilities have been discovered in Adobe Acrobat and Adobe Reader, the most severe of which could allow for remote 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.

THREAT INTELLIGENCE:

There are currently no reports of these vulnerabilities being exploited in the wild.

SYSTEMS AFFECTED:

  • Adobe Acrobat DC versions 2017.012.20098 and prior for Windows and Macintosh
  • Adobe Acrobat Reader DC versions 2017.012.20098 and prior for Windows and Macintosh
  • Acrobat 2017 versions 2017.011.30066 and prior for Windows and Macintosh
  • Acrobat Reader 2017 versions 2017.011.30066 and prior for Windows and Macintosh
  • Adobe Acrobat DC versions 2015.006.30355 and prior for Windows and Macintosh
  • Adobe Acrobat Reader DC versions 2015.006.30355 and prior for Windows and Macintosh
  • Adobe Acrobat XI versions 11.0.22 and prior for Windows and Macintosh
  • Adobe Reader XI versions 11.0.22 and prior for Windows and Macintosh

RISK:

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

TECHNICAL SUMMARY:

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

  • Two access of uninitialized point vulnerabilities that could result in remote could execution (CVE-2017-16377, CVE-2017-16378).
  • Six use after free vulnerabilities that could result in remote code execution (CVE-2017-16360, CVE-2017-16388, CVE-2017-16389, CVE-2017-16390, CVE-2017-16393, CVE-2017-16398).
  • Five buffer access with incorrect length value vulnerabilities that could result in remote code execution (CVE-2017-16381, CVE-2017-16385, CVE-2017-16392, CVE-2017-16395, CVE-2017-16396).
  • Six buffer over-read vulnerabilities that could result in remote code execution (CVE-2017-16363, CVE-2017-16365, CVE-2017-16374, CVE-2017-16384, CVE-2017-16386, CVE-2017-16387)

  • A heap overflow vulnerability that could result in remote code execution (CVE-2017-16383).
  • Two improper validation of array index vulnerabilities that could result in remote code execution (CVE-2017-16391, CVE-2017-16410).
  • Multiple out-of-bounds read vulnerabilities that could result in remote code execution (CVE-2017-16362, CVE-2017-16370, CVE-2017-16376, CVE-2017-16382, CVE-2017-16394, CVE-2017-16397, CVE-2017-16399, CVE-2017-16400, CVE-2017-16401, CVE-2017-16402, CVE-2017-16403, CVE-2017-16404, CVE-2017-16405, CVE-2017-16408, CVE-2017-16409, CVE-2017-16412, CVE-2017-16414, CVE-2017-16417, CVE-2017-16418, CVE-2017-16420, CVE-2017-11293).
  • Four out-of-bounds write vulnerabilities that could result in remote code execution (CVE-2017-16407, CVE-2017-16413, CVE-2017-16415, CVE-2017-16416).
  • Two security bypass vulnerabilities that could result in drive-by-downloads (CVE-2017-16361, CVE-2017-16366).
  • A security bypass vulnerability that could result in information disclosure (CVE-2017-16369).
  • A security bypass vulnerability that could result in remote code execution (CVE-2017-16380).
  • A stack exhaustion vulnerability that could result in excessive resource consumption (CVE-2017-16419)
  • Three type confusion vulnerabilities that could result in remote code execution (CVE-2017-16367, CVE-2017-16379, CVE-2017-16406)
  • Six untrusted pointer dereference vulnerabilities that could result in remote code execution (CVE-2017-16364, CVE-2017-16371, CVE-2017-16372, CVE-2017-16373, CVE-2017-16375, CVE-2017-16411)

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.

RECOMENDATIONS:

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 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.
  • Apply the Principle of Least Privilege to all systems and services.
