Vulnerability in Oracle Java SE (component: 2D). Supported versions that are affected are Oracle Java SE: 25.0.4 and 26.0.2. 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 7.5 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).
A flaw was found in OpenJDK. A remote attacker could cause a denial of service (DoS) by supplying a specially crafted font file. Processing the malicious font triggers an unrecoverable exception during a Foreign Function and Memory (FFM) API upcall, forcing the Java Virtual Machine (JVM) to terminate unexpectedly.
Отчет
This vulnerability is evaluated as a Moderate severity issue because, while an attacker can cause denial of service by terminating the runtime process, it does not allow privilege escalation or unauthorized data exposure. Exploitation requires a Java application to parse or render externally supplied font files using Foreign Function and Memory interfaces. Common production environments running supported Long Term Support versions, such as OpenJDK 17 and 21, are not affected as the vulnerable code is not present.
