MS-ISAC ADVISORY NUMBER:
2016-038

DATE(S) ISSUED:
03/08/2016

SUBJECT:
Multiple Vulnerabilities in Adobe Acrobat and Adobe Reader Could Allow for Remote Code Execution (APSB16-09)

OVERVIEW:

Multiple vulnerabilities in Adobe Acrobat and Adobe Reader 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 could potentially allow an attacker to take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full system rights.

THREAT INTELLIGENCE:

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

SYSTEMS AFFECTED:

  • Adobe Acrobat DC version prior to 15.010.20059 for Windows and Macintosh
  • Acrobat Reader DC version prior to 15.010.20059 for Windows and Macintosh
  • Acrobat DC version prior to 15.006.30119 for Windows and Macintosh
  • Adobe Acrobat Reader DC version prior to 15.006.30119 for Windows and Macintosh
  • Adobe Acrobat XI version prior to 11.0.14 Windows and Macintosh
  • Adobe Reader XI version prior to 11.0.14 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:

    Adobe Acrobat and Reader are prone to multiple vulnerabilities, the most severe of which could allow for remote code execution. These vulnerabilities are as follows:

    • Memory corruption vulnerabilities that could lead to code execution. (CVE-2016-1007, CVE-2016-1009)
    • Vulnerability in the directory search path used to find resources that could lead to code execution. (CVE-2016-1008)
    • Successful exploitation could potentially allow an attacker to take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full system rights.

    RECOMMENDATIONS:

    We recommend the following actions be taken:
    • Install the updates provided by Adobe immediately after appropriate testing.
    • Remind users not to visit websites or follow links provided by unknown or untrusted sources.
