Descriptions

An issue was discovered in ReadyTalk Avian 1.2.0 before 2020-10-27. The FileOutputStream.write() method in FileOutputStream.java has a boundary check to prevent out-of-bounds memory read/write operations. However, an integer overflow leads to bypassing this check and achieving the out-of-bounds access. NOTE: This vulnerability only affects products that are no longer supported by the maintainer

Se detectó un problema en ReadyTalk Avian versión 1.2.0 antes del 27-10-2020. El método FileOutputStream.write() en el archivo FileOutputStream.java presenta una verificación de límites para evitar operaciones de lectura/escritura de memoria fuera de límites. Sin embargo, un desbordamiento de enteros conduce a omitir esta verificación y lograr el acceso fuera de límites. NOTA: Esta vulnerabilidad solo afecta a los productos que ya no son compatibles con el mantenedor
