Sun Java: Web Start argument injection vulnerability Java Web Start JNLP files can be abused to evade sandbox restriction and execute arbitrary code. Java March 24, 2005 May 22, 2006: 02 85804 remote 1.4.2.07 1.4.2 1.4.2.07 1.4.2.07 1.4.2 1.4.2.07

Sun provides implementations of Java Development Kits (JDK) and Java Runtime Environments (JRE). These implementations provide the Java Web Start technology that can be used for easy client-side deployment of Java applications.

Jouko Pynnonen discovered that Java Web Start contains a vulnerability in the way it handles property tags in JNLP files.

By enticing a user to open a malicious JNLP file, a remote attacker could pass command line arguments to the Java Virtual machine, which can be used to bypass the Java "sandbox" and to execute arbitrary code with the permissions of the user running the application.

There is no known workaround at this time.

All Sun JDK users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=dev-java/sun-jdk-1.4.2.07"

All Sun JRE users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=dev-java/sun-jre-bin-1.4.2.07" Jouko Pynnonen advisory Sun Microsystems Alert Notification CVE-2005-0836 koon koon formula7
