Description

A flaw was found in t-digest. A remote attacker can exploit a vulnerability in the `MergingDigest.fromBytes` deserialization process by injecting specially crafted "Not a Number" (NaN) values. These malicious values bypass validation checks, degrading sorting performance from efficient to significantly slower. This can lead to severe processing delays during merge operations, resulting in a Denial of Service (DoS) for the affected system.
