Description

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

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)
