This post concerns issues in Windows [not us/9X] IE, and other,. the second
segment concerns exploits in PDF documents.
As 9x can not use the newer Reader versions, disable Java, html
connections, and other aspects in the 9X reader [see its settings to
disable], or use something like Foxit Reader to help avoid potential issues.
Your firewall can also be used to block Adobe Reader's access to the outside
world.

Adobe Reader and Acrobat Vulnerabilities

Original release date: February 12, 2008
Last revised: --
Source: US-CERT


Systems Affected

* Adobe Reader version 8.1.1 and earlier
* Adobe Acrobat Professional, 3D, and Standard versions 8.1.1 and
earlier


Overview

Adobe has released Security advisory APSA08-01 to address multiple
vulnerabilities affecting Adobe Reader and Acrobat. The most severe of
these vulnerabilities could allow a remote attacker to execute
arbitrary code.


I. Description

Adobe Security advisory APSA08-01 addresses a number of
vulnerabilities affecting the Adobe Acrobat family of products,
including Adobe Reader. Acrobat versions 8.1.1 and earlier are
affected. Further details are available in the US-CERT Vulnerability
Notes Database.

An attacker could exploit these vulnerabilities by convincing a user
to load a specially crafted Adobe Portable Document Format (PDF) file.
Acrobat integrates with popular web browsers, and visiting a web site
is usually sufficient to cause Acrobat to load PDF content.

At least one of these vulnerabilities is being actively exploited. The
SANS Internet Storm Center Handler's Diary contains more information.


II. Impact

The impacts of these vulnerabilities vary. The most severe of these
vulnerabilities allows a remote attacker to execute arbitrary code.


III. Solution

Upgrade

Upgrade Adobe Reader or Acrobat to version 8.1.2 according to the
information in Adobe Security advisory APSA08-01.


Disable web browser display for PDF documents

Preventing PDF documents from opening inside a web browser may
mitigate this vulnerability. Applying the following workaround in
conjunction with upgrading may prevent similar vulnerabilities from
being automatically exploited.

To prevent PDF documents from automatically being opened in a web
browser with Acrobat or Reader:
1. Open Adobe Acrobat or Adobe Reader.
2. Open the Edit menu.
3. Choose the Preferences option.
4. Choose the Internet section.
5. De-select the "Display PDF in browser" check box.


Disable automatic opening of PDF documents in Microsoft Internet Explorer

To disable automatic opening of PDF files in Microsoft Internet
Explorer (IE), a second step is required. To configure IE to prompt
before opening a PDF file, disable the "Display PDF in browser"
feature (as described above) and then make the following changes to
the Windows registry:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\AcroExch.Document.7]
"EditFlags"=hex:00,00,00,00


Disable JavaScript in Adobe Reader and Acrobat

Disabling JavaScript in Adobe Reader and Acrobat may prevent this
vulnerability from being exploited. In Acrobat Reader, JavaScript can
be disabled in the General preferences dialog (Edit --> Preferences
--> JavaScript, de-select Enable Acrobat JavaScript).

Sun Updates for Multiple Vulnerabilities in Java

Original release date: March 6, 2008
Last revised: --
Source: US-CERT


Systems Affected

Sun Java Runtime Environment versions
* JDK and JRE 6 Update 4 and earlier
* JDK and JRE 5.0 Update 14 and earlier
* SDK and JRE 1.4.2_16 and earlier
* SDK and JRE 1.3.1_21 and earlier


Overview

Sun has released alerts to address multiple vulnerabilities affecting
the Sun Java Runtime Environment. The most severe of these
vulnerabilities could allow a remote attacker to execute arbitrary
code.


I. Description

The Sun Java Runtime Environment (JRE) allows users to run Java
applications in a browser or as standalone programs. Sun has released
updates to the Java Runtime Environment software to address multiple
vulnerabilities. Further details about these vulnerabilities are
available in the US-CERT Vulnerability Notes Database.

Sun released the following alerts to address these issues:
* 233321 Two Security Vulnerabilities in the Java Runtime
Environment Virtual Machine

* 233322 Security Vulnerability in the Java Runtime Environment With
the Processing of XSLT Transformations

* 233323 Multiple Security Vulnerabilities in Java Web Start May
Allow an Untrusted Application to Elevate Privileges

* 233324 A Security Vulnerability in the Java Plug-in May Allow an
Untrusted Applet to Elevate Privileges

* 233325 Vulnerabilties in the Java Runtime Environment image
Parsing Library

* 233326 Security Vulnerability in the Java Runtime Environment May
Allow Untrusted JavaScript Code to Elevate Privileges Through Java
APIs

* 233327 Buffer Overflow Vulnerability in Java Web Start May Allow
an Untrusted Application to Elevate its Privileges


II. Impact

The impacts of these vulnerabilities vary. The most severe of these
vulnerabilities allows a remote attacker to execute arbitrary code.


III. Solution

Apply an update from Sun

These issues are addressed in the following versions of the Sun Java
Runtime environment:
* JDK and JRE 6 Update 5 or later
* JDK and JRE 5.0 Update 15 or later
* SDK and JRE 1.4.2_17 or later
* SDK and JRE 1.3.1_21 and earlier

If you install the latest version of Java, older versions of Java may
remain installed on your computer. If these versions of Java are not
needed, you may wish to remove them. For instructions on how to remove
older versions of Java, refer to the following instructions from Sun.

Disable Java

Disable Java in your web browser, as specified in the Securing Your
Web Browser document. While this does not fix the underlying
vulnerabilities, it does block a common attack vector.
