Multiple Vulnerabilities in Adobe Acrobat and Adobe Reader Could Allow for Code Execution

MS-ISAC ADVISORY NUMBER:

2017-035

DATE(S) ISSUED:

04/11/2017

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.

THREAT INTELLIGENCE:

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

SYSTEMS AFFECTED:

  • Adobe Acrobat DCversions 15.023.20070and prior for Windows and Macintosh
  • AdobeAcrobat Reader DC versions15.023.20070and prior for Windows and Macintosh
  • AdobeAcrobat DC versions 15.006.30280and prior for Windows and Macintosh
  • Adobe Acrobat Reader DC versions 15.006.30280and prior for Windows and Macintosh
  • Adobe Acrobat XI versions 11.0.19and prior for Windows and Macintosh
  • Adobe Reader XI versions 11.0.19and prior for Windows and Macintosh

RISK:

Goverment:
  • 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 code execution. The vulnerabilities are as follows:

  • Sixuse-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).

  • Fourheap 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.

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.
