Synopsis
Critical: Adobe Acrobat Reader security update
Type/Severity
Security Advisory: Critical
Topic
Updated acroread packages that fix several security issues are now
available for Red Hat Enterprise Linux 3.
This update has been rated as having critical security impact by the Red
Hat Security Response Team.
[Updated 23 Jan 2007]
The previous acroread packages were missing dependencies on the new
libraries which could prevent acroread from starting. Replacement acroread
packages have been added to this erratum to correct this issue.
Description
The Adobe 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)
Please note that Adobe Reader 7.0.9 requires versions of several system
libraries that were not shipped with Red Hat Enterprise Linux 3. This
update contains additional packages that provide the required system
library versions for Adobe Reader. These additional packages are only
required by Adobe Reader and do not replace or affect any other aspects of
a Red Hat Enterprise Linux 3 system.
All users of Adobe Reader are advised to upgrade to these updated packages,
which contain Adobe Reader version 7.0.9 and additional libraries to
correct 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.
