SUBJECT:                 Multiple Vulnerabilities in Adobe Flash Player Could Allow Remote Code

Execution

 

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.

 

It should be noted that these vulnerabilities are currently being exploited via various phishing campaigns.

 

 

DESCRIPTION:

Adobe Flash Player is prone to multiple vulnerabilities that could allow for remote code execution.  The update provided by Adobe resolves the following:

 

  • A permissions issue with the Flash Player Firefox sandbox.
  • A vulnerability in the External Interface Action Script feature, which can be exploited to execute malicious code.
  • A buffer overflow vulnerability in a Flash Player broker service, which can be used to execute malicious code.

 

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. 

 

According to Adobe, the first two vulnerabilities listed above are being exploited in the wild in attacks delivered via malicious Flash (SWF) content hosted on websites that target Flash Player in Firefox.

 

 

SYSTEM AFFECTED:

  • Adobe Flash Player 11.6.602.168 and earlier versions for Windows
  • Adobe Flash Player 11.6.602.167 and earlier versions for Macintosh
  • Adobe Flash Player 11.2.202.270 and earlier versions for Linux
  • Adobe Flash Player 10.3.183.61 and earlier versions for Linux

 

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

 

RECOMMENDATIONS:

 

We recommend the following actions be taken:

 

  • Install the updates provided by Adobe immediately after appropriate testing.
  • Users of Adobe Flash Player 11.6.602.168 and earlier versions for Windows should update to Adobe Flash Player 11.6.602.171.
  • Users of Adobe Flash Player 11.6.602.167 and earlier versions for Macintosh should update to Adobe Flash Player 11.6.602.171.
  • Users of Adobe Flash Player 11.2.202.270 and earlier versions for Linux should update to Adobe Flash Player 11.2.202.273.
  • 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.
  • Do not open email attachments from unknown or un-trusted sources.
