Advisory ID:       RHSA-2007:0017-01
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2007-0017.html
Issue date:        2007-01-11
Updated on:        2007-01-11
Product:           Red Hat Enterprise Linux Extras

1. Summary:

Updated acroread packages that fix several security issues are now
available for Red Hat Enterprise Linux 4.

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 Extras - i386, x86_64
Red Hat Desktop version 4 Extras - i386, x86_64
Red Hat Enterprise Linux ES version 4 Extras - i386, x86_64
Red Hat Enterprise Linux WS version 4 Extras - i386, x86_64

3. Problem description:

The Adobe Acrobat 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)

All users of Acrobat Reader are advised to upgrade to these updated
packages, which contain Acrobat Reader version 7.0.9 and are not vulnerable
to these issues.

4. Solution:

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

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade.  Only those
RPMs which are currently installed will be updated.  Those RPMs which are
not installed but included in the list will not be updated.  Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network.  Many
people find this an easier way to apply updates.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

5. Bug IDs fixed (http://bugzilla.redhat.com/):

221594 - CVE-2006-5857 Multiple Acrobat vulnerabilities (CVE-2007-0045 CVE-2007-0046)
