NVD Description

Note: Versions mentioned in the description apply only to the upstream zstd-jni-java package and not the zstd-jni-java package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

zstd-jni versions before 1.5.7-14 fail to validate closed state in setDict, setLongMax, setLevel and setRefMultipleDDicts methods of stream classes. Attackers can call these methods on closed streams to write through freed native pointers, corrupting unrelated objects or crashing the JVM.
