The JNLP SecurityManager in IcedTea (IcedTea.so) 1.7 before 1.7.7, 1.8 before 1.8.4, and 1.9 before 1.9.4 for Java OpenJDK returns from the checkPermission method instead of throwing an exception in certain circumstances, which might allow context-dependent attackers to bypass the intended security policy by creating instances of ClassLoader.

Security readout for executives and security teams

This is an old IcedTea Java client vulnerability where a JNLP security check could fail open. In affected versions, a hostile or untrusted Java Web Start context may bypass intended security restrictions by creating ClassLoader instances. It mainly matters where legacy IcedTea/OpenJDK browser or JNLP support is still present. Exposure is most likely on legacy Linux desktops or servers with old IcedTea/OpenJDK JNLP or browser-plugin packages installed. Modern systems are unlikely to be exposed unless they retain obsolete Java Web Start workflows or archived enterprise images. Treat as a legacy exposure cleanup item. It is not KEV-listed in the provided bundle, but any remaining affected Java Web Start or browser-plugin footprint should be removed or patched because sandbox bypasses can become serious when paired with user interaction. Mitigation focus: Upgrade IcedTea/OpenJDK packages using the relevant vendor advisory packages.; Remove or disable unused IcedTea JNLP and browser-plugin components.; Prioritize systems that still open untrusted JNLP or Java Web Start content..
