Overview
Affected versions of this package are vulnerable to Infinite loop due to negative length validation in read(byte[], int, int) in src/main/java/com/github/luben/zstd/ZstdInputStreamNoFinalizer.java. An attacker can spin a caller thread indefinitely by supplying a negative len to read(), which leaves the method retrying without making progress. Because the method is synchronized, the stuck read holds the stream’s monitor and blocks other threads that try to use the same ZstdInputStreamNoFinalizer instance, causing a thread-exhaustion denial of service.
