CIS CYBER SECURITY ADVISORIES

MS-ISAC CYBER SECURITY ADVISORY NUMBER:
2013-109

DATE(S) ISSUED:
12/10/2013

SUBJECT:
Multiple Vulnerabilities in Adobe Flash Player Could Allow Remote Code Execution (APSB13-28)

OVERVIEW:

Multiple vulnerabilities have been discovered in Adobe Flash Player that could allow an attacker to take control of the affected system. Adobe Flash Player is a widely distributed multimedia and application player used to enhance the user experience when visiting web pages or reading email messages. Successful exploitation could result in an attacker gaining the same privileges as the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Failed exploit attempts will likely cause denial-of-service conditions.

SYSTEMS AFFECTED:

  • Adobe Flash Player 11.9.900.152 and earlier versions for Windows and Macintosh
  • Adobe Flash Player 11.2.202.327 and earlier versions for Linux
  • Adobe AIR 3.9.0.1210 and earlier versions for Windows, Macintosh and Android
  • Adobe AIR 3.9.0.1210 SDK and earlier versions
  • Adobe AIR 3.9.0.1210 SDK & Compiler and earlier versions

RISK:

Government:

  • Large and medium government entities: High
  • Small government entities: High

Businesses:

  • Large and medium business entities: High
  • Small business entities: High

Home users: High

DESCRIPTION:

Adobe Flash Player is prone to multiple vulnerabilities that could allow for remote code execution. Specifically, the vulnerabilities identified may allow an attacker to corrupt the application's memory in such a way that results in remote code execution. Failed exploitation attempts may cause denial-of-service conditions. Successful exploitation could result in an attacker gaining the same privileges as the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Failed exploit attempts will likely cause denial-of-service conditions.

RECOMMENDATIONS:

We recommend the following actions be taken:

  • Install the updates provided by Adobe immediately after appropriate testing.
  • Remind users not to visit untrusted websites or follow links provided by unknown or untrusted sources.
  • Do not open email attachments from unknown or untrusted sources.
