RHSA-2008:0144 - Security Advisory

Topic

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

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

Description

The Adobe Reader allows users to view and print documents in portable
document format (PDF).

Several flaws were found in the way Adobe Reader processed malformed PDF
files. An attacker could create a malicious PDF file which could execute
arbitrary code if opened by a victim. (CVE-2007-5659, CVE-2007-5663,
CVE-2007-5666, CVE-2008-0726)

A flaw was found in the way the Adobe Reader browser plug-in honored
certain requests. A malicious PDF file could cause the browser to request
an unauthorized URL, allowing for a cross-site request forgery attack.
(CVE-2007-0044)

A flaw was found in Adobe Reader's JavaScript API DOC.print function. A
malicious PDF file could silently trigger non-interactive printing of the
document, causing multiple copies to be printed without the users consent.
(CVE-2008-0667)

Additionally, this update fixes multiple unknown flaws in Adobe Reader.
When the information regarding these flaws is made public by Adobe, it will
be added to this advisory. (CVE-2008-0655)

Note: Adobe have yet to release security fixed versions of Adobe 7. All
users of Adobe Reader are, therefore, advised to install these updated
packages. They contain Adobe Reader version 8.1.2, which is not vulnerable
to these issues.

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.
