SUBJECT: Multiple Vulnerabilities in Adobe Flash Player and AIR Could Allow Remote Code Execution

OVERVIEW:

Multiple vulnerabilities have been discovered in Adobe Flash Player and Adobe AIR that could allow attackers to take complete control of affected systems. Adobe Flash Player and Adobe AIR are widely distributed multimedia’s and application players used to enhance the user experience when visiting web pages or reading email messages.

Successful exploitation 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 rights. Failed exploit attempts will likely cause denial-of-service conditions.

DESCRIPTION:

Adobe Flash Player is prone to twenty-four vulnerabilities that could allow for remote code execution. The vulnerabilities are as follows:

Multiple memory-corruption vulnerabilities that may result in code-execution.
Multiple buffer-overflow vulnerability that may result in code-execution.
