Summary

Vulnerability in the JAXP component of Oracle Java SE, Oracle GraalVM for JDK and Oracle GraalVM Enterprise Edition. An unauthenticated attacker with network access can cause a partial denial of service (partial DoS). The vulnerability also applies to Java deployments running untrusted code in a sandbox.

Risk Assessment

A remote, unauthenticated attacker can partially disrupt the availability of Java applications, potentially causing service interruptions. The risk is especially relevant for internet-facing systems and environments running untrusted code.

Recommendation

Update Oracle Java SE, Oracle GraalVM for JDK and Oracle GraalVM Enterprise Edition to the versions containing Oracle's fix. Verify that applications using JAXP do not process untrusted data from the network.
