RHSA-2009:0478 - Security Advisory

Topic

Updated acroread packages that fix two 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.

Description

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

Two flaws were discovered in Adobe Reader's JavaScript API. A PDF file
containing malicious JavaScript instructions could cause Adobe Reader to
crash or, potentially, execute arbitrary code as the user running Adobe
Reader. (CVE-2009-1492, CVE-2009-1493)

All Adobe Reader users should install these updated packages. They contain
Adobe Reader version 8.1.5, which is not vulnerable to these issues. All
running instances of Adobe Reader must be restarted for the update to take
effect.
