Multiple Vulnerabilities in Adobe Products Could Allow for Arbitrary Code Execution

DESCRIPTION:
Multiple vulnerabilities have been discovered in Adobe products, the
most severe of which could allow for Arbitrary Code Execution.

* Acrobat and Reader is a family of application software and Web
services mainly used to create, view, and edit PDF documents.
* Illustrator is a vector graphics editor and design program.
* Bridge is a digital asset management application.
* Adobe InCopy is a professional word processor.
* InDesign is an industry-leading layout and page design software for
print and digital media.

Successful exploitation of the most severe of these vulnerabilities
could allow for arbitrary code execution. Depending on the privileges
associated with the user, an attacker could then install programs; view,
change, or delete data; or create new accounts with full user rights.
Users whose accounts are configured to have fewer user rights on the
system could be less impacted than those who operate with administrative
user rights.

IMPACT:
Multiple vulnerabilities have been discovered in Adobe Products, the
most severe of which could allow for arbitrary code execution. Details
of these vulnerabilities are as follows:

RECOMMENDATIONS:
We recommend the following actions be taken:

* Install the updates provided by Adobe immediately after appropriate
testing.
* Run all software as a non-privileged user (one without administrative
privileges) to diminish the effects of a successful attack.
* Remind users not to visit un-trusted websites or follow links provided
by unknown or un-trusted sources.
* Inform and educate users regarding the threats posed by hypertext
links contained in emails or attachments especially from un-trusted sources.
* Apply the Principle of Least Privilege to all systems and services.
