Synopsis

Critical: acroread security and bug fix update

Type/Severity

Security Advisory: Critical

Topic

Updated acroread packages that fix two security issues and a bug are now
available for 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).

This update fixes two vulnerabilities in Adobe Reader. These
vulnerabilities are summarized on the Adobe Security Advisory APSB10-07
page 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-2010-0186, CVE-2010-0188)

This update also fixes a bug where, on some systems, attempting to install
or upgrade the acroread packages failed due to a package dependency issue.
(BZ#557506)

All Adobe Reader users should install these updated packages. They contain
Adobe Reader version 9.3.1, which is not vulnerable to these issues and
fixes this bug. All running instances of Adobe Reader must be restarted for
the update to take effect.
