Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound in the findDirectByteBufferFrameCompressedSize, decompressedDirectByteBufferSize, and getDirectByteBufferFrameContentSize native handlers in src/main/native/jni_zstd.c. An attacker can crash the JVM or trigger an out-of-bounds read by supplying crafted src_offset and src_size values to these direct ByteBuffer frame-size queries, including values near Integer.MIN_VALUE that wrap the 32-bit arithmetic used in the capacity check.
