REDHAT-BUG-2557356: Medium severity Oracle Java SE vulnerability
Vulnerability in Oracle Java SE (component: JSSE). Supported versions that are affected are Oracle Java SE: 8u503, 8u503-perf, 11.0.32.1, 17.0.20.1, 21.0.12.1, 25.0.4.1; Oracle GraalVM for JDK: 17.0.20.1 and 21.0.12.1; Oracle GraalVM Enterprise Edition: 21.3.19.1.1. Easily exploitable vulnerability allows unauthenticated attacker with network access via TLS to compromise Oracle Java SE. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial 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 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).

Frequently Asked Questions
Which deployments are most exposed to this issue?
Systems running the affected Oracle Java SE or GraalVM releases are exposed when an unauthenticated attacker can reach them over TLS. Java client deployments running sandboxed Java Web Start applications or sandboxed applets that load untrusted internet-originated code are also affected when they rely on the Java sandbox for security.
What does an attacker need to exploit it?
The attacker needs network access via TLS and does not need authentication, privileges, or user interaction. Exploitation may occur through a web service that supplies attacker-controlled data to APIs in the affected JSSE component.
What is the expected impact of successful exploitation?
Successful exploitation can cause a partial denial of service in Oracle Java SE. The stated CVSS 3.1 vector has low availability impact and no confidentiality or integrity impact.
Which versions are identified as affected?
Affected Oracle Java SE versions are 8u503, 8u503-perf, 11.0.32.1, 17.0.20.1, 21.0.12.1, and 25.0.4.1. Affected Oracle GraalVM for JDK versions are 17.0.20.1 and 21.0.12.1, and Oracle GraalVM Enterprise Edition 21.3.19.1.1 is also affected.
