Oracle Java SE Denial of Service Vulnerability

Publication date: 2026-08-26

Last updated on: 2026-08-26

Assigner: Oracle

Description

Vulnerability in Oracle Java SE (component: 2D). Supported versions that are affected are Oracle Java SE: 7u511. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Java SE. Note: This vulnerability can be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. This vulnerability also applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. CVSS 3.1 Base Score 6.5 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L).

Attack-Flow Graph

Executive Summary

This is a vulnerability in Oracle Java SE, specifically in the 2D component. It affects version 7u511 and allows an unauthenticated attacker with network access to cause a denial of service (DOS) by crashing or hanging the Java SE system. The vulnerability can be exploited through APIs or web services that process untrusted data.

Detection Guidance

This vulnerability affects Oracle Java SE 7u511 and can be exploited via APIs or web services. Detection involves checking Java versions and monitoring for crashes or hangs. Use commands like 'java -version' to verify installed versions and 'jcmd <pid> VM.version' to check running Java processes.

Impact Analysis

If you use Oracle Java SE 7u511, an attacker could exploit this flaw to crash your Java applications, leading to service disruptions. Systems running sandboxed Java Web Start or applets that load untrusted code are also at risk.

Compliance Impact

This vulnerability primarily causes denial-of-service (DOS) conditions in Oracle Java SE, which may impact system availability. Compliance with standards like GDPR or HIPAA often requires maintaining data availability and integrity; however, this issue does not directly lead to data breaches or unauthorized access. Its impact is limited to service disruption rather than data exposure or compliance violations.

Mitigation Strategies

Immediately update Oracle Java SE to a patched version. If updating is not possible, restrict network access to Java applications, disable Java Web Start and applets, and monitor for suspicious activity targeting the 2D component.
