Description

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 are detailed in the Adobe Security Bulletin APSB14-14,
listed in the References section.

Multiple flaws were found in the way flash-plugin displayed certain SWF

arbitrary code when the victim loaded a page containing the malicious SWF
content. (CVE-2014-0510, CVE-2014-0517, CVE-2014-0518, CVE-2014-0519,

upgrades Flash Player to version 11.2.202.359.
