3. 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 APSB14-24,
listed in the References section.
Multiple 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. (CVE-2014-0573, CVE-2014-0574, CVE-2014-0576, CVE-2014-0577,
CVE-2014-0581, CVE-2014-0582, CVE-2014-0584, CVE-2014-0585, CVE-2014-0586,

CVE-2014-8441)
This update also fixes an information disclosure flaw in flash-plugin that
could allow a remote attacker to obtain a victim's session cookie.
(CVE-2014-8437)

upgrades Flash Player to version 11.2.202.418.
