Descriptions

The class file parser in IBM Java before 1.4.2 SR13 FP9, as used in IBM Runtimes for Java Technology 5.0.0 before SR13 and 6.0.0 before SR10, allows remote authenticated users to cause a denial of service (JVM segmentation fault, and possibly memory consumption or an infinite loop) via a crafted attribute length field in a class file, which triggers a buffer over-read.

El analizador de archivos de clases en IBM Java antes de v1.4.2 SR13 FP9, tal como se utiliza en IBM Runtimes para Java Technology v5.0.0 antes de SR13 y v6.0.0 antes de SR10, permite a usuarios autenticados remotamente provocar una denegación de servicio (fallo de segmentación de JVM, y posiblemente, el consumo de memoria o un bucle infinito) a través de un campo de atributo de longitud modificada en un archivo de clase, lo que provoca una sobrelectura de buffer.

The IBM 1.4.2 SR13-FP9 Java release includes the IBM Java 2 Runtime Environment and the IBM Java 2 Software Development Kit. This update fixes several vulnerabilities in the IBM Java 2 Runtime Environment and the IBM Java 2 Software Development Kit. Detailed vulnerability descriptions are linked from the IBM "Security alerts" page, listed in the References section. All users of java-1.4.2-ibm-sap for Red Hat Enterprise Linux 4, 5 and 6 for SAP are advised to upgrade to these updated packages, which contain the IBM 1.4.2 SR13-FP9 Java release. All running instances of IBM Java must be restarted for this update to take effect. Various other issues were also addressed.
