yawkat LZ4 Java: LZ4BlockInputStream allocates an unvalidated compressed length from the stream header

Summary LZ4BlockInputStream grows its compressed-input buffer to the attacker-controlled compressedLen value from the legacy LZ4Block stream header before reading any payload bytes. A header-only input can therefore trigger a near-2 GiB allocation and exhaust the JVM heap. Details In...
