Ubuntu Security Notice USN-1506-1
July 12, 2012

puppet vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in Puppet.

Software Description:
- puppet: Centralized configuration management

Details:

It was discovered that Puppet incorrectly handled certain HTTP GET
requests. An attacker could use this flaw with a valid client certificate
to retrieve arbitrary files from the Puppet master. (CVE-2012-3864)

It was discovered that Puppet incorrectly handled Delete requests. If a
Puppet master were reconfigured to allow the "Delete" method, an attacker
on an authenticated host could use this flaw to delete arbitrary files from
the Puppet server, leading to a denial of service. (CVE-2012-3865)

It was discovered that Puppet incorrectly set file permissions on the
last_run_report.yaml file. An attacker could use this flaw to access
sensitive information. This issue only affected Ubuntu 11.10 and Ubuntu
12.04 LTS. (CVE-2012-3866)

It was discovered that Puppet incorrectly handled agent certificate names.
An attacker could use this flaw to create a specially crafted certificate
and trick an administrator into signing a certificate that can then be used
to man-in-the-middle agent nodes. (CVE-2012-3867)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
puppet-common 2.7.11-1ubuntu2.1

Ubuntu 11.10:
puppet-common 2.7.1-1ubuntu3.7

Ubuntu 11.04:
puppet-common 2.6.4-2ubuntu2.10

Ubuntu 10.04 LTS:
puppet-common 0.25.4-2ubuntu6.8

In general, a standard system update will make all the necessary changes.

Ubuntu Security Notice USN-1505-1

icedtea-web, openjdk-6 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in OpenJDK 6.

Software Description:
- openjdk-6: Open Source Java implementation
- icedtea-web: A web browser plugin to execute Java applets

Details:

It was discovered that multiple flaws existed in the CORBA (Common
Object Request Broker Architecture) implementation in OpenJDK. An
attacker could create a Java application or applet that used these
flaws to bypass Java sandbox restrictions or modify immutable object
data. (CVE-2012-1711, CVE-2012-1719)

It was discovered that multiple flaws existed in the OpenJDK font
manager's layout lookup implementation. A attacker could specially
craft a font file that could cause a denial of service through
crashing the JVM (Java Virtual Machine) or possibly execute arbitrary
code. (CVE-2012-1713)

It was discovered that the SynthLookAndFeel class from Swing in
OpenJDK did not properly prevent access to certain UI elements
from outside the current application context. An attacker could
create a Java application or applet that used this flaw to cause a
denial of service through crashing the JVM or bypass Java sandbox
restrictions. (CVE-2012-1716)

It was discovered that OpenJDK runtime library classes could create
temporary files with insecure permissions. A local attacker could
use this to gain access to sensitive information. (CVE-2012-1717)

It was discovered that OpenJDK did not handle CRLs (Certificate
Revocation Lists) properly. A remote attacker could use this to gain
access to sensitive information. (CVE-2012-1718)

It was discovered that the OpenJDK HotSpot Virtual Machine did not
properly verify the bytecode of the class to be executed. A remote
attacker could create a Java application or applet that used this
to cause a denial of service through crashing the JVM or bypass Java
sandbox restrictions. (CVE-2012-1723, CVE-2012-1725)

It was discovered that the OpenJDK XML (Extensible Markup Language)
parser did not properly handle some XML documents. An attacker could
create an XML document that caused a denial of service in a Java
application or applet parsing the document. (CVE-2012-1724)

As part of this update, the IcedTea web browser applet plugin was
updated for Ubuntu 10.04 LTS, Ubuntu 11.04, and Ubuntu 11.10.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
openjdk-6-jre 6b24-1.11.3-1ubuntu0.12.04.1

Ubuntu 11.10:
icedtea-6-plugin 1.2-2ubuntu0.11.10.1
openjdk-6-jre 6b24-1.11.3-1ubuntu0.11.10.1

Ubuntu 11.04:
icedtea-6-plugin 1.2-2ubuntu0.11.04.1
openjdk-6-jre 6b24-1.11.3-1ubuntu0.11.04.1

Ubuntu 10.04 LTS:
icedtea-6-plugin 1.2-2ubuntu0.10.04.1
openjdk-6-jre 6b24-1.11.3-1ubuntu0.10.04.1

This update uses a new upstream release, which includes additional
bug fixes. After a standard system update you need to restart any
Java applications or applets to make all the necessary changes.
