Subject: 
Multiple Vulnerabilities in Adobe Flash Player Could Allow Remote Code Execution (APSB15-01)
Overview: 

Multiple vulnerabilities in Adobe Flash Player may allow remote code execution. 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 install programs; view, change, or delete data; or create

  • Adobe Flash Player 16.0.0.235 and earlier versions
  • Adobe Flash Player 13.0.0.259 and earlier 13.x versions
  • Adobe Flash Player 11.2.202.425 and earlier versions for Linux

Description: 

 Versions of Abobe Flash player identified above are prone to the following vulnerabilities:

  • An improper file validation issue (CVE-2015-0301). 
  • An information disclosure vulnerability that could be exploited to capture keystrokes on the affected system (CVE-2015-0302). 
  • Memory corruption vulnerabilities that could lead to code execution (CVE-2015-0303, CVE-2015-0306). 
  • Heap-based buffer overflow vulnerabilities that could lead to code execution (CVE-2015-0304, CVE-2015-0309). 
  • A type confusion vulnerability that could lead to code execution (CVE-2015-0305).
  • An out-of-bounds read vulnerability that could be exploited to leak memory addresses (CVE-2015-0307). 
  • A
    use-after-free vulnerability that could lead to code execution (CVE-2015-0308).

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 install programs; view, change, or delete data; or create new accounts with full system access.
