SUBJECT: Vulnerabilities in Adobe Flash Player Could Allow For Remote Code Execution

OVERVIEW:

Multiple vulnerabilities have been discovered in Adobe Flash Player that could allow an attacker to take control of the affected system. 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 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 multiple vulnerabilities that could allow for remote code execution. Details of these vulnerabilities are as follows:

An unspecified memory corruption vulnerability exists in Adobe Flash Player that could allow remote code execution. (CVE-2012-4163, CVE-2012-4164, CVE-2012-4165, CVE-2012-4166).

An unspecified integer overflow vulnerability exists in Adobe Flash Player that could allow remote code execution (CVE-2012-4167).

An unspecified cross-domain information leak vulnerability exists in Adobe Flash Player (CVE-2012-4168).

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.
