Summary
A flaw was found in zstd-jni. This use-after-free vulnerability occurs because streams and contexts only hold a dictionary's shared lock during the load call, allowing the dictionary to be closed while still being referenced.
A remote attacker could exploit this by closing a dictionary after associating it with a stream or context. Subsequent read or write operations would then access freed native memory, leading to silent data corruption or a Java Virtual Machine (JVM) crash, resulting in a denial of service.
