Critical: acroread security update

Updated acroread packages that fix multiple security issues are now
available for Red Hat Enterprise Linux 3 Extras, Red Hat Enterprise Linux 4
Extras, and Red Hat Enterprise Linux 5 Supplementary.

This update has been rated as having critical security impact by the Red
Hat Security Response Team.

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

Multiple input validation flaws were discovered in the JBIG2 compressed
images decoder used by Adobe Reader. A malicious PDF file could cause Adobe
Reader to crash or, potentially, execute arbitrary code as the user running
Adobe Reader. (CVE-2009-0193, CVE-2009-0658, CVE-2009-0928, CVE-2009-1061,
CVE-2009-1062)

All Adobe Reader users should install these updated packages. They contain
Adobe Reader version 8.1.4, which is not vulnerable to these issues. All
running instances of Adobe Reader must be restarted for the update to take
effect.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
