Multiple Vulnerabilities in Adobe Flash Player Could Allow Remote Code Execution (APSB15-05)
MS-ISAC ADVISORY NUMBER:2015-028
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 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 126.96.36.1995 and earlier versions
- Adobe Flash Player 188.8.131.529 and earlier 13.x versions
- Large and medium government entities: HIGH
- Small government entities: HIGH

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 restrictionbypass (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.
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.
