Subject: 
Multiple Vulnerabilities in Adobe Flash Player Could Allow Remote Code Execution (APSB15-05)
Overview: 

Multiple vulnerabilities have been discovered in Adobe Flash Player. 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 of these vulnerabilities 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 access. Failed exploit attempts will likely cause denial-of-service conditions.

March 20 - UPDATED OVERVIEW:

The exploit listed in CVE-2015-0336 has been confirmed to be included in the Nuclear Exploit Kit and are actively being used in the wild. Using this vulnerability, the Nuclear Exploit Kit can compromise victim machines in order to deliver malware.

Systems Affected: 
  • Adobe Flash Player 16.0.0.305 and earlier versions
  • Adobe Flash Player 13.0.0.269 and earlier 13.x versions
  • Adobe Flash Player 13.0.0.269 and earlier 13.x versions

Description: 

Adobe Flash Player is prone to multiple vulnerabilities that could allow for remote code execution. These vulnerabilities are as follows:

  • Memory corruption vulnerabilities that may lead to code execution (CVE-2015-0332, CVE-2015-0333, CVE-2015-0335, CVE-2015-0339).
  • Type confusion vulnerabilities that may lead to code execution (CVE-2015-0334, CVE-2015-0336).
  • A vulnerability that could lead to a cross-domain policy bypass (CVE-2015-0337).
  • A vulnerability that may lead to a file upload restriction bypass (CVE-2015-0340).
  • An integer overflow vulnerability that could lead to code execution (CVE-2015-0338).
  • Use-after-free vulnerabilities that could lead to code execution (CVE-2015-0341, CVE-2015-0342).                                                                                                                   

Successful exploitation of these vulnerabilities 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 access.
