The remote Red Hat host is missing one or more security updates.
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.
Update the affected acroread and / or acroread-plugin packages.
