CVE-2026-87962 t-digest 3.1 through 3.3 Denial of Service via Unvalidated Length Fields in MergingDigest.fromBytes

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...

CVE-2026-87962

t-digest versions 3.1 through 3.3 (a Java library for approximate quantile estimation maintained by tdunning on GitHub) contain a denial of service vulnerability in MergingDigest.fromBytes . The root cause is a failure to validate length and capacity fields read from serialized data; a crafted se...
