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 APSB14-16,
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-2014-0534, CVE-2014-0535, CVE-2014-0536)
Multiple flaws in flash-plugin could allow an attacker to conduct
cross-site scripting (XSS) attacks if a victim were tricked into visiting a
specially crafted web page. (CVE-2014-0531, CVE-2014-0532, CVE-2014-0533)
All users of Adobe Flash Player should install this updated package, which
upgrades Flash Player to version 11.2.202.378.
