Description

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.
