NVD Description

Note: Versions mentioned in the description apply only to the upstream zstd-jni package and not the zstd-jni package as distributed by SLES. See How to fix? for SLES:16.0.0 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.
