Details

t-digest versions 3.1 through 3.3 contain a denial of service vulnerability in MergingDigest.fromBytes that fails to validate length and capacity fields from serialized data. Attackers can supply crafted serialized digests with mismatched header fields to trigger ArrayIndexOutOfBoundsException or NegativeArraySizeException, aborting the parsing thread.
