Descriptions

In Eclipse OpenJ9 release versions prior to 0.44.0 and after 0.13.0, when running with JVM option -Xgc:concurrentScavenge, the sequence generated for System.arrayCopy on the IBM Z platform with hardware and software support for guarded storage [1], could allow access to a buffer with an incorrect length value when executing an arraycopy sequence while the Concurrent Scavenge Garbage Collection cycle is active and the source and destination memory regions for arraycopy overlap. This allows read and write to addresses beyond the end of the array range.

En las versiones de Eclipse OpenJ9 anteriores a 0.44.0 y posteriores a 0.13.0, cuando se ejecuta con la opción JVM -Xgc:concurrentScavenge, la secuencia generada para System.arrayCopy en la plataforma IBM Z con soporte de hardware y software para almacenamiento protegido [1], podría permitir el acceso a un búfer con un valor de longitud incorrecto al ejecutar una secuencia de copia de matriz mientras el ciclo de recolección de basura de recuperación concurrente está activo y las regiones de memoria de origen y destino para la copia de matriz se superponen. Esto permite leer y escribir en direcciones más allá del final del rango de la matriz.
