ITS Advisory Number: 
2014-112
Date(s) Issued: 
Tuesday, December 9, 2014
Subject: 
Multiple Vulnerabilities in Adobe Flash Player Could Allow Remote Code Execution (APSB14-27)
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 new accounts with full user access. Failed exploit attempts will likely cause denial-of-service conditions.

Systems Affected: 
  • Adobe Flash Player for Windows and Macintosh before version 16.0.0.235
  • Adobe Flash Player Extended Support Release before version 13.0.0.259
  • Adobe Flash Player for Linux before version 11.2.202.425

Description: 

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

  • Memory corruption vulnerabilities that could lead to code execution (CVE-2014-0587, CVE-2014-9164).
  • Use-after-free vulnerability that could lead to code execution (CVE-2014-8443).
  • Stack-based buffer overflow vulnerability that could lead to code execution (CVE-2014-9163).
  • Information disclosure vulnerability (CVE-2014-9162).
  • A vulnerability that could be exploited to circumvent the same-origin policy (CVE-2014-0580).

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 user access.

We recommend the following actions be taken:

  • Install the updates provided by Adobe immediately after appropriate testing.
