A flaw was found in the way flash-plugin displayed certain SWF content. An
attacker could use this flaw 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 specially-crafted SWF content.
(CVE-2012-0768)

A flaw in flash-plugin could allow an attacker to obtain sensitive
information if a victim were tricked into visiting a specially-crafted web
