Description

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

This update fixes multiple vulnerabilities in Adobe Reader. These
vulnerabilities are detailed on the Adobe security page APSB10-21, listed
in the References section.

A specially-crafted PDF file could cause Adobe Reader to crash or,
potentially, execute arbitrary code as the user running Adobe Reader when
opened. (CVE-2010-2883, CVE-2010-2884, CVE-2010-2889, CVE-2010-2890,
CVE-2010-3619, CVE-2010-3620, CVE-2010-3621, CVE-2010-3622, CVE-2010-3625,
CVE-2010-3626, CVE-2010-3627, CVE-2010-3628, CVE-2010-3629, CVE-2010-3630,
CVE-2010-3632, CVE-2010-3658)

An insecure relative RPATH (runtime library search path) set in some Adobe
Reader libraries could allow a local attacker, who is able to convince
another user to run Adobe Reader in an attacker-controlled directory, to
execute arbitrary code with the privileges of the victim. (CVE-2010-2887)

A specially-crafted PDF file could cause Adobe Reader to crash when opened.
(CVE-2010-3656, CVE-2010-3657)

All Adobe Reader users should install these updated packages. They contain
Adobe Reader version 9.4, which is not vulnerable to these issues. All
running instances of Adobe Reader must be restarted for the update to take
effect.
