Summary: zstd-jni 1.2.0 through 1.5.7-13 Out-of-Bounds Read via ZstdDictCompress
Details: zstd-jni versions before 1.5.7-14 fail to validate offset and length parameters in the ZstdDictCompress constructor, allowing out-of-bounds memory reads. Attackers can supply untrusted offset or length values to read native heap memory into the compression dictionary, typically causing JVM crashes.
