Adobe Reader allows users to view and print documents in Portable Document
Format (PDF).

This update fixes multiple security flaws in Adobe Reader. These flaws are
detailed on the Adobe security page APSB11-24, listed in the References

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-2011-2440, 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,

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)

All Adobe Reader users should install these updated packages. They contain
Adobe Reader version 9.4.6, which is not vulnerable to these issues. All
running instances of Adobe Reader must be restarted for the update to take
effect.
