The remote host is missing updates announced in advisory RHSA-2009:0334. The flash-plugin package contains a Firefox-compatible Adobe Flash Player Web browser plug-in. Multiple input validation flaws were found in the way Flash Player displayed certain SWF (Shockwave Flash) content. An attacker could use these flaws to create a specially-crafted SWF file that could cause flash-plugin to crash, or, possibly, execute arbitrary code when the victim loaded a page containing the specially-crafted SWF content. (CVE-2009-0520, CVE-2009-0519) All users of Adobe Flash Player should install this updated package, which upgrades Flash Player to version 22.214.171.124.
