Multiple Vulnerabilities in Adobe Acrobat and Reader Could Allow for Arbitrary Code Execution (APSB18-02)

MS-ISAC ADVISORY NUMBER:

2018-021

DATE(S) ISSUED:

02/13/2018

OVERVIEW:

Multiple vulnerabilities have been discovered in Adobe Acrobat and Reader, the most severe of which could allow for arbitrary 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 an attacker executing arbitrary code in the context of the affected application. 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 (Continuous Track) for Windows and Macintosh versions 2018.009.20050 and earlier
  • Adobe Acrobat Reader DC (Continuous Track) for Windows and Macintosh versions 2018.009.20050 and earlier
  • Adobe Acrobat 2017 for Windows and Macintosh versions 2017.011.30070 and earlier
  • Adobe Acrobat Reader 2017 for Windows and Macintosh versions 2017.011.30070 and earlier
  • Adobe Acrobat DC (Classic Track) for Windows and Macintosh versions 2015.006.30394 and earlier
  • Adobe Acrobat Reader DC (Classic Track) for Windows and Macintosh versions 2015.006.30394 and earlier

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 Reader, the most severe of which could allow for arbitrary code execution. The vulnerabilities are as follows:

  • One security mitigation bypass vulnerability that could allow for privilege escalation (CVE-2018-4872)
  • Four heap overflow vulnerabilities that could allow for arbitrary code execution (CVE-2018-4890, CVE-2018-4904, CVE-2018-4910, CVE-2018-4917)
  • Five use-after-free vulnerabilities that could allow for arbitrary code execution (CVE-2018-4888, CVE-2018-4892, CVE-2018-4902, CVE-2018-4911, CVE-2018-4913)
  • Seven out-of-bounds write vulnerabilities that could allow for arbitrary code execution (CVE-2018-4879, CVE-2018-4895, CVE-2018-4898, CVE-2018-4901, CVE-2018-4915, CVE-2018-4916, CVE-2018-4918)
  • Twenty-four out-of-bounds read vulnerabilities that could allow for remote code execution (CVE-2018-4880, CVE-2018-4881, CVE-2018-4882, CVE-2018-4883, CVE-2018-4884, CVE-2018-4885, CVE-2018-4886, CVE-2018-4887, CVE-2018-4889, CVE-2018-4891, CVE-2018-4893, CVE-2018-4894, CVE-2018-4896, CVE-2018-4897, CVE-2018-4899, CVE-2018-4900, CVE-2018-4903, CVE-2018-4905, CVE-2018-4906, CVE-2018-4907, CVE-2018-4908, CVE-2018-4909, CVE-2018-4912, CVE-2018-4914)

Successful exploitation of the most severe of these vulnerabilities could result in an attacker executing arbitrary code in the context of the affected application. 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.
