This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Adobe Flash. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the handling of instanceof. The issue lies in the failure to safely hold a reference to arguments during execution of the function. An attacker can leverage this vulnerability to execute arbitrary code under the context of the current process.

The flash-plugin package contains a Mozilla Firefox compatible Adobe Flash Player web browser plug-in. This update fixes multiple vulnerabilities in Adobe Flash Player. These vulnerabilities, detailed in the Adobe Security Bulletin APSB16-04 listed in the References section, could allow an attacker to create a specially crafted SWF file that would cause flash-plugin to crash, execute arbitrary code, or disclose sensitive information when the victim loaded a page containing the malicious SWF content.
