Description OSIDB Bzimport 2026-09-10 17:51:34 UTC 
zstd-jni versions 1.4.8-4 through 1.5.7-13 fail to validate negative length parameters in ZstdInputStreamNoFinalizer.read(), allowing attackers to trigger infinite loops. Attackers can pass negative length values to cause the read method to spin indefinitely while holding the stream monitor, blocking all other threads from accessing the stream.
