The flash-plugin package contains a Mozilla Firefox compatible Adobe Flash

This update fixes two vulnerabilities in Adobe Flash Player. These
vulnerabilities are detailed in the Adobe Security Bulletin APSB15-18
listed in the References section.
Two flaws were found in the way flash-plugin displayed certain SWF content.
An attacker could use these flaws to create a specially crafted SWF file
that would cause flash-plugin to crash or, potentially, execute arbitrary
code when the victim loaded a page containing the malicious SWF content.
