Descriptions

Vulnerability in the Java SE, Java SE Embedded component of Oracle Java SE (subcomponent: JGSS). Supported versions that are affected are Java SE: 7u161, 8u152 and 9.0.1; Java SE Embedded: 8u151. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. While the vulnerability is in Java SE, Java SE Embedded, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Java SE, Java SE Embedded accessible data. Note: This vulnerability 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. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS 3.0 Base Score 6.8 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N).

Vulnerabilidad en los componentes Java SE y Java SE Embedded de Oracle Java SE (subcomponente: JGSS). Las versiones compatibles que se han visto afectadas son JavaSE: 7u161, 8u152 y 9.0.1; Java SE Embedded: 8u151. Una vulnerabilidad difícilmente explotable permite que un atacante sin autenticar que tenga acceso a red por múltiples protocolos comprometa la seguridad de Java SE y Java SE Embedded. Aunque la vulnerabilidad está presente en Java SE y Java SE Embedded, los ataques podrían afectar ligeramente a productos adicionales. Los ataques exitosos a esta vulnerabilidad pueden resultar en un acceso no autorizado a datos de suma importancia o un acceso completo a todos los datos accesibles de Java SE y Java SE Embedded. Nota: Esta vulnerabilidad se aplica a implementaciones Java, normalmente en clientes que ejecutan aplicaciones Java Web Start en sandbox o applets Java en sandbox que cargan y ejecutan código que no es de confianza (por ejemplo, código proveniente de internet) y que confían en la sandbox de aislado Java para protegerse. Esta vulnerabilidad no se aplica a implementaciones Java, normalmente en servidores, que solo cargan y ejecutan código de confianza (por ejemplo, código instalado por un administrador). CVSS 3.0 Base Score 6.8 (impactos en la confidencialidad). Vector CVSS: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N).

The JGSS component of OpenJDK ignores the value of the javax.security.auth.useSubjectCredsOnly property when using HTTP/SPNEGO authentication and always uses global credentials. It was discovered that this could cause global credentials to be unexpectedly used by an untrusted Java application.
