Prezados,

A Microsoft publicou 13 boletins de segurança em 13 de dezembro que 
abordam ao todo 17 vulnerabilidades em produtos da empresa. A exploração 
destas vulnerabilidades permitem execução remota de código e elevação de 
privilégio.

 - Nenhum boletim


O sistema de classificação de severidade das vulnerabilidades adotado pelo 
CAIS neste resumo é o da própria Microsoft. O CAIS recomenda que se 
aplique, minimamente, as correções para vulnerabilidades classificadas 
como crítica e importante. No caso de correções para vulnerabilidades 
classificadas como moderadas o CAIS recomenda que ao menos as 
recomendações de mitigação sejam seguidas.

. Crítica - Vulnerabilidades cuja exploração possa permitir a propagação
  de um worm sem a necessidade de interação com o usuário.

. Importante - Vulnerabilidades cuja exploração possa resultar no
  comprometimento de confidencialidade, integridade ou disponibilidade
  de dados de usuários ou a integridade ou disponibilidade de recursos
  de processamento.

. Moderada - exploração é mitigada significativamente por fatores como
  configuração padrão, auditoria ou dificuldade de exploração.

. Baixa - uma vulnerabilidade cuja exploração seja extremamente difícil
  ou cujo impacto seja mínimo.


CORREÇÕES DISPONÍVEIS

Recomenda-se atualizar os sistemas para as versões disponíveis em:

. Microsoft Update
  https://www.update.microsoft.com/microsoftupdate/

. Windows Server Update Services

Adobe Updates for Multiple Vulnerabilities

   Original release date: December 16, 2011
   Last revised: --
   Source: US-CERT


Systems Affected

     * Adobe Reader X (10.1.1) and earlier 10.x versions for Windows and Macintosh
     * Adobe Reader 9.4.6 and earlier 9.x versions for Windows, Macintosh, and UNIX
     * Adobe Acrobat X (10.1.1) and earlier 10.x versions for Windows and Macintosh
     * Adobe Acrobat 9.4.6 and earlier 9.x versions for Windows and Macintosh


Overview

   Adobe has released Security Bulletin APSB11-30, which describes
   multiple vulnerabilities affecting Adobe Reader and Acrobat.


I. Description

   Adobe Security Bulletin APSB11-30 and Adobe Security Advisory
   APSA11-04 describe a number of vulnerabilities affecting Adobe
   Reader and Acrobat. These vulnerabilities affect Reader and Acrobat
   9.4.6 and earlier 9.x versions. These vulnerabilities also affect
   Reader X and Acrobat X 10.1.1 and earlier 10.x versions.

   An attacker could exploit these vulnerabilities by convincing a
   user to open a specially crafted PDF file. The Adobe Reader browser
   plug-in, which can automatically open PDF documents hosted on a
   website, is available for multiple web browsers and operating
   systems.

   Adobe Reader X and Adobe Acrobat X will be patched in the next
   quarterly update scheduled for January 10, 2012.

   Additional details for the U3D memory corruption vulnerability can
   be found in US-CERT Vulnerability Note VU#759307.


II. Impact

   These vulnerabilities could allow a remote attacker to execute
   arbitrary code, write arbitrary files or folders to the file
   system, escalate local privileges, or cause a denial of service on
   an affected system as the result of a user opening a malicious PDF
   file.


III. Solution

   Update Reader

   Adobe has released updates to address this issue. Users are
   encouraged to read Adobe Security Bulletin APSB11-30 and update
   vulnerable versions of Adobe Reader and Acrobat.

   In addition to updating, please consider the following mitigations.

   Disable Flash in Adobe Reader and Acrobat

   Disabling Flash in Adobe Reader will mitigate attacks that rely on
   Flash content embedded in a PDF file. Disabling 3D & Multimedia
   support does not directly address the vulnerability, but it does
   provide additional mitigation and results in a more user-friendly
   error message instead of a crash. To disable Flash and 3D &
   Multimedia support in Adobe Reader 9, delete, rename, or remove
   access to these files:

   Microsoft Windows
   "%ProgramFiles%\Adobe\Reader 9.0\Reader\authplay.dll"
   "%ProgramFiles%\Adobe\Reader 9.0\Reader\rt3d.dll"

   Apple Mac OS X
   "/Applications/Adobe Reader 9/Adobe
   Reader.app/Contents/Frameworks/AuthPlayLib.bundle"
   "/Applications/Adobe Reader 9/Adobe
   Reader.app/Contents/Frameworks/Adobe3D.framework"

   GNU/Linux (locations may vary among distributions)
   "/opt/Adobe/Reader9/Reader/intellinux/lib/libauthplay.so"
   "/opt/Adobe/Reader9/Reader/intellinux/lib/librt3d.so"

   File locations may be different for Adobe Acrobat or other Adobe
   products that include Flash and 3D & Multimedia support. Disabling
   these plugins will reduce functionality and will not protect
   against Flash content that is hosted on websites. Depending on the
   update schedule for products other than Flash Player, consider
   leaving Flash and 3D & Multimedia support disabled unless they are
   absolutely required.

   Disable JavaScript in Adobe Reader and Acrobat

   Disabling JavaScript may prevent some exploits from resulting in
   code execution. Acrobat JavaScript can be disabled using the
   Preferences menu (Edit -> Preferences -> JavaScript; uncheck Enable
   Acrobat JavaScript).

   Adobe provides a framework to blacklist specific JavaScipt APIs. If
   JavaScript must be enabled, this framework may be useful when
   specific APIs are known to be vulnerable or used in attacks.

   Prevent Internet Explorer from automatically opening PDF files

   The installer for Adobe Reader and Acrobat configures Internet
   Explorer to automatically open PDF files without any user
   interaction. This behavior can be reverted to a safer option that
   prompts the user by importing the following as a .REG file:

   Windows Registry Editor Version 5.00

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

   Disable the display of PDF files in the web browser

   Preventing PDF files from opening inside a web browser will
   partially mitigate this vulnerability. If this workaround is
   applied, it may also mitigate future vulnerabilities.

   To prevent PDF files from automatically being opened in a web
   browser, do the following:

   1. Open Adobe Acrobat Reader.
   2. Open the Edit menu.
   3. Choose the Preferences option.
   4. Choose the Internet section.
   5. Uncheck the "Display PDF in browser" checkbox.

   Remove or restrict access to 3difr.x3d

   By removing or restricting access to the 3difr.x3d file, Adobe
   Reader and Acrobat will fail to render U3D content, which helps to
   mitigate this vulnerability. PDF documents that use the PRC format
   for 3D content will continue to function on Windows and Linux
   platforms.

   To disable U3D support in Adobe Reader 9 on Microsoft Windows,
   delete or rename this file:

       "%ProgramFiles%\Adobe\Reader 9.0\Reader\plug_ins3d\3difr.x3d"

   For Apple Mac OS X, delete or rename this directory:

   "/Applications/Adobe Reader 9/Adobe
   Reader.app/Contents/Frameworks/Adobe3D.framework"

   For GNU/Linux, delete or rename this file (locations may vary among
   distributions):

       "/opt/Adobe/Reader9/Reader/intellinux/plug_ins3d/3difr.x3d"

   File locations may be different for Adobe Acrobat or other Adobe
   products or versions.

   Do not access PDF files from untrusted sources

   Do not open unfamiliar or unexpected PDF files, particularly those
   hosted on websites or delivered as email attachments. Please see
   Cyber Security Tip ST04-010.
