potentially, execute arbitrary code as the user running Adobe Reader when
opened. (CVE-2011-2431, CVE-2011-2432, CVE-2011-2433, CVE-2011-2434,
CVE-2011-2435, CVE-2011-2436, CVE-2011-2437, CVE-2011-2438, CVE-2011-2439,
CVE-2011-2440, CVE-2011-2442)

This update also fixes multiple security flaws in Adobe Flash Player
embedded in Adobe Reader. These flaws are detailed on the Adobe security
pages APSB11-21 and APSB11-26, listed in the References section.

A PDF file with an embedded, specially-crafted SWF file could cause Adobe
Reader to crash or, potentially, execute arbitrary code as the user running
Adobe Reader when opened. (CVE-2011-2130, CVE-2011-2134, CVE-2011-2135,
CVE-2011-2136, CVE-2011-2137, CVE-2011-2138, CVE-2011-2139, CVE-2011-2140,

CVE-2011-2425, CVE-2011-2426, CVE-2011-2427, CVE-2011-2428, CVE-2011-2430)

A flaw in Adobe Flash Player 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 Adobe Flash
Player. (CVE-2011-2429)
