MS-ISAC CYBER SECURITY ADVISORY NUMBER:
Multiple Vulnerabilities in Adobe Flash Player Could Allow Remote Code Execution (APSB14-27)
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 could result in an attacker compromising data security, potentially allowing access to confidential data, or could compromise processing resources in a user's computer. Failed exploit attempts will likely cause denial-of-service conditions.
This vulnerability is actively being exploited in the wild by multiple exploit kits.
- Adobe Flash Player for Windows and Macintosh before version 126.96.36.199
- Adobe Flash Player Extended Support Release before version 188.8.131.529
- Adobe Flash Player for Linux before version 184.108.40.2065

Adobe Flash Player is 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 then 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.
- Remind users not to visit untrusted websites or follow links provided by unknown or untrusted sources.
- Do not open email attachments from unknown or untrusted sources.
- Limit user account privileges to those required only.
