Critical Nessus Plugin ID 65099
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionUSN-1079-1 fixed vulnerabilities in OpenJDK 6 for non-armel (ARM) architectures. This update provides the corresponding updates for OpenJDK 6 for use with the armel (ARM) architectures.
In order to build the armel (ARM) OpenJDK 6 update for Ubuntu 10.04 LTS, it was necessary to rebuild binutils and gcj-4.4 from Ubuntu 10.04 LTS updates.
It was discovered that untrusted Java applets could create domain name resolution cache entries, allowing an attacker to manipulate name resolution within the JVM. (CVE-2010-4448)
It was discovered that the Java launcher did not did not properly setup the LD_LIBRARY_PATH environment variable. A local attacker could exploit this to execute arbitrary code as the user invoking the program. (CVE-2010-4450)

This could allow an attacker to access restricted resources.
It was discovered that certain bytecode combinations confused memory management within the HotSpot JVM. This could allow an attacker to cause a denial of service through an application crash or possibly inject code.
It was discovered that the way JAXP components were handled allowed them to be manipulated by untrusted applets. An attacker could use this to bypass XML processing restrictions and elevate privileges. (CVE-2010-4470)
It was discovered that the Java2D subcomponent, when processing broken CFF fonts could leak system properties.
It was discovered that a flaw in the XML Digital Signature component could allow an attacker to cause untrusted code to replace the XML Digital Signature Transform or C14N algorithm implementations. (CVE-2010-4472)
Konstantin Preisser and others discovered that specific double literals were improperly handled, allowing a remote attacker to cause a denial of service. (CVE-2010-4476)

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected icedtea6-plugin, openjdk-6-jre and / or openjdk-6-jre-headless packages.
