Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: JSSE). Supported versions that are affected are Oracle Java SE: 8u501, 11.0.32, 17.0.20, 21.0.12, 25.0.4, 26.0.2; Oracle GraalVM for JDK: 17.0.20 and 21.0.12; Oracle GraalVM Enterprise Edition: 21.3.19. Easily exploitable vulnerability allows unauthenticated attacker with network access via TLS to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Note: This vulnerability can only be exploited by supplying data to APIs in the specified Component without using Untrusted Java Web Start applications or Untrusted Java applets, such as through a web service. CVSS 3.1 Base Score 5.3 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).
A flaw was found in OpenJDK. An unauthenticated remote attacker can cause a Denial of Service (DoS) by repeatedly sending replayed handshake initiation messages (ClientHello) to a Transport Layer Security (TLS) server. Because the server fails to properly restrict the negotiation loop, it emits an unbounded number of retry requests (HelloRetryRequest), consuming server resources.
Отчет
This flaw is assessed as having a Moderate impact because an unauthenticated remote attacker can cause resource exhaustion, but cannot execute arbitrary code, escalate privileges, or compromise confidential data. In Red Hat environments, exposure is limited to server applications running on OpenJDK that directly accept and terminate TLS 1.3 connections. Deployments fronted by reverse proxies or load balancers that handle TLS termination beforehand, as well as Java client applications, are not affected.
