Overview
Affected versions of this package are vulnerable to Out-of-bounds Read through Zstd.trainFromBufferDirect0 in src/main/native/jni_zdict.c. An attacker can crash the JVM by supplying a direct samples buffer with an oversized sampleSizes array whose total length exceeds the buffer’s actual capacity. The native dictionary trainer passes the caller-provided lengths to ZDICT_trainFromBuffer without checking that they fit within the direct buffer, so it reads past the end of the sample data and can terminate applications that train dictionaries from untrusted input.
