National Cyber Awareness System
TA13-064A: Oracle Java Contains Multiple Vulnerabilities

Original release date: March 05, 2013

Systems Affected

 * Any system using Oracle Java 7, 6, 5 (1.7, 1.6, 1.5) including
 * Java Platform Standard Edition 7 (Java SE 7)
 * Java Platform Standard Edition 6 (Java SE 6)
 * Java Platform Standard Edition 6 (Java SE 5)
 * Java SE Development Kit (JDK 7)
 * Java SE Development Kit (JDK 6)
 * Java SE Development Kit (JDK 5)
 * Java SE Runtime Environment (JRE 7)
 * Java SE Runtime Environment (JRE 6)
 * Java SE Runtime Environment (JRE 5)
 * OpenJDK 6 and 6u
 * IcedTea 1.x (IcedTea6 1.x)

All versions of Java 7 through update 15, Java 6 through update 41, and
Java 5.0 through update 40 are affected. Web browsers using
the Java 5, 6 or 7 plug-in are at high risk.

Overview

Oracle Java 7 update 15, Java 6 update 41, Java 5.0 update 40, and
earlier versions of Java contain a vulnerability that can allow a
remote, unauthenticated attacker to execute arbitrary code on a
vulnerable system.

Description

An arbitrary memory read and write vulnerability in the Java JVM process
could allow an attacker to execute arbitrary code. An attacker could use
social engineering techniques to entice a user to visit a link to a
website hosting a malicious Java applet. An attacker could also
compromise a legitimate website and upload a malicious Java applet (a
"drive-by download" attack).
Any web browser using the Java 5, 6, or 7 plug-in is affected. The Java
Deployment Toolkit plug-in and Java Web Start can also be used as attack
vectors.
Reports indicate this vulnerability is being actively exploited, and
exploit code is publicly available.
Further technical details are available in Vulnerability Note VU#688246.

Impact

By convincing a user to load a malicious Java applet or Java Network
Launching Protocol (JNLP) file, an attacker could execute arbitrary code
on a vulnerable system with the privileges of the Java plug-in process.
Note that applications that use the Internet Explorer web-content-
rendering components, such as Microsoft Office or Windows Desktop
Search, may also be used as an attack vector for these vulnerabilities.

Solution

Update Java
Oracle Security Alert for CVE-2013-1493 states that Java 7 Update 17
(7u17) and and Java 6 Update 43 address this vulnerability (CVE-2013-
1493) and a different but equally severe vulnerability (CVE-2013-0809).
Java 7 Update 17 sets the default Java security settings to "High" so
that users will be prompted before running unsigned or self-signed Java
applets.

Disable Java in Web Browsers
This and previous Java vulnerabilities have been widely targeted by
attackers, and new Java vulnerabilities are likely to be discovered. To
defend against these vulnerabilities, consider disabling Java in web
browsers until adequate updates are available. As with any software,
unnecessary features should be disabled or removed as appropriate for
your environment.
Starting with Java 7 Update 10, it is possible to disable Java content
in web browsers through the Java control panel applet. According to
Setting the Security Level of the Java Client,
For installations where the highest level of security is required, it is
possible to entirely prevent any Java apps (signed or unsigned) from
running in a browser by de-selecting Enable Java content in the browser
in the Java Control Panel under the Security tab.
If you are unable to update to Java 7 Update 10, see the solution
section of Vulnerability Note VU#636312 for instructions on how to
disable Java on a per-browser basis.

-----BEGIN PGP SIGNED MESSAGE-----

Prezados,

A Microsoft publicou 7 boletins de segurança em 12 de março de 2013
que abordam ao todo 20 vulnerabilidades em produtos da empresa. A
exploração destas vulnerabilidades permitem execução remota de código,
elevação de privilégios, vazamento de informações, entre outros.

Até o momento da publicação, existe a provável exploração de uma ou mais
vulnerabilidades contidas no boletim MS13-021.


SEVERIDADE

. Crítica

- - MS13-021 - Atualizações de segurança cumulativas para o Internet 
Explorer.

- - MS13-022 - Vulnerabilidades no Microsoft Silverlight podem
             permitir a execução remota de código.

- - MS13-023 - Vulnerabilidades no visualizador Microsoft Visio 2010 podem
             permitir a execução remota de código.

- - MS13-024 - Vulnerabilidades no Microsoft SharePoint podem
             permitir elevação de privilégio.


. Importante

- - MS13-025 - Vulnerabilidades no Microsoft OneNote podem permitir
             vazamento de informações.

- - MS13-026 - Vulnerabilidades no Microsoft Office Outlook para usuários
             Mac podem permitir vazamento de informações.

- - MS13-027 - Vulnerabilidade no driver do modo do kernel do Windows
             pode permitir a elevação de privilégio.

. Moderada

- - Nenhum boletim


. Baixa

- - 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
