CIS CYBER SECURITY ADVISORIES
MS-ISAC CYBER SECURITY ADVISORY NUMBER:
Multiple Vulnerabilities in Adobe Flash Player and Adobe AIR Could Allow Remote Code Execution (APSB14-21)
Multiple vulnerabilities have been discovered in Adobe Flash Player and Adobe AIR. 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. Adobe AIR is a cross platform runtime used for developing Internet applications that run outside of a browser.
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.
There are currently no reports of these vulnerabilities being exploited in the wild.

Adobe Flash Player is prone to multiple vulnerabilities that could allow for remote code execution. These vulnerabilities are as follows:
- Memory corruption vulnerabilities that could lead to code execution (CVE-2014-0547, CVE-2014-0549, CVE-2014-0550, CVE-2014-0551, CVE-2014-0552, CVE-2014-0555).
- A vulnerability that could be used to bypass the same origin policy (CVE-2014-0548).
- A use-after-free vulnerability that could lead to code execution (CVE-2014-0553).
- A security bypass vulnerability (CVE-2014-0554).
- A heap buffer overflow vulnerability that could lead to code execution (CVE-2014-0556, CVE-2014-0559).
- Memory leakage vulnerabilities that could be used to bypass memory address randomization (CVE-2014-0557).
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.
