Relevant releases/architectures: Red Hat Enterprise Linux Desktop Supplementary (v. 5) - i386, x86_64 Red Hat Enterprise Linux Desktop Supplementary (v. 6) - i386, x86_64 Red Hat Enterprise Linux Server Supplementary (v. 5) - i386, x86_64 Red Hat Enterprise Linux Server Supplementary (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Supplementary (v. 6) - i386, x86_64 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 on the Adobe security page APSB11-26, listed in the References section. Multiple security 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 specially-crafted SWF content. (CVE-2011-2426, CVE-2011-2427, CVE-2011-2428, CVE-2011-2430) A flaw 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-2011-2444) This update also fixes an information disclosure flaw in flash-plugin. (CVE-2011-2429) All users of Adobe Flash Player should install this updated package, which upgrades Flash Player to version 10.3.183.10. 4.
