ITS ADVISORY NUMBER:
2012-082

DATE(S) ISSUED:
11/06/2012

SUBJECT:
Multiple Vulnerabilities in Adobe Flash Player Could Allow Remote Code Execution (APSB12-24)

OVERVIEW:

Multiple vulnerabilities have been discovered in Adobe Flash Player that could allow attackers to take complete control of affected systems. Adobe Flash Player is a widely distributed multimedia and application player used to enhance the user experience when visiting web pages or reading e-mail 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 11.4.402.287 and earlier versions for Windows and Macintosh
  • Adobe Flash Player 11.2.202.243 and earlier versions for Linux
  • Adobe Flash Player 11.1.115.20 and earlier versions for Android 4.x
  • Adobe Flash Player 11.1.111.19 and earlier versions for Android 3.x and 2.x
  • Flash Player 11.4.402.287 and earlier for Chrome users
  • Flash Player 11.3.375.10 and earlier in Internet Explorer 10
  • Adobe AIR 3.4.0.2710 and earlier versions for Windows, Macintosh and Android
  • Adobe 3.4.0.2710 SDK (includes AIR for iOS) 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 twenty-four vulnerabilities that could allow for remote code execution. The vulnerabilities are as follows:

  • Multiple buffer overflow vulnerabilities that could lead to code execution (CVE-2012-5274, CVE-2012-5275, CVE-2012-5276, CVE-2012-5277, CVE-2012-5280).
  • A memory corruption vulnerability that could lead to code execution (CVE-2012-5279)
  • A security bypass vulnerability that could lead to code execution (CVE-2012-5278)

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.
  • 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 un-trusted websites or follow links provided by unknown or un-trusted sources.
  • Remind users not to open e-mail attachments from unknown users or suspicious e-mails from trusted sources.
