(RHSA-2007:0021) Critical: Adobe Acrobat Reader security update

The Adobe Reader allows users to view and print documents in portable
document format (PDF).

A cross site scripting flaw was found in the way the Adobe Reader Plugin
processes certain malformed URLs. A malicious web page could inject
arbitrary javascript into the browser session which could possibly lead to
a cross site scripting attack. (CVE-2007-0045)

Two arbitrary code execution flaws were found in the way Adobe Reader
processes malformed document files. It may be possible to execute arbitrary
code on a victim’s machine if the victim opens a malicious PDF file.
(CVE-2006-5857, CVE-2007-0046)

Please note that Adobe Reader 7.0.9 requires versions of several system
libraries that were not shipped with Red Hat Enterprise Linux 3. This
update contains additional packages that provide the required system
library versions for Adobe Reader. These additional packages are only
required by Adobe Reader and do not replace or affect any other aspects of
a Red Hat Enterprise Linux 3 system.

All users of Adobe Reader are advised to upgrade to these updated packages,
which contain Adobe Reader version 7.0.9 and additional libraries to
correct these issues.
