SUBJECT:
Multiple Vulnerabilities In Adobe Flash Player Could Allow Remote Code Execution (APSB15-04)

OVERVIEW:

Multiple vulnerabilities in Adobe Flash Player could 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.
