Out-of-bounds Write vulnerability in Apache DataSketches C++. An
application that deserializes a KLL sketch from an untrusted source
can have heap memory corrupted by a crafted sketch, because the
serialized level boundaries were not validated.
This issue affects Apache DataSketches C++: 2.0.0 through 5.3.0.
Users are recommended to upgrade to version 5.3.1, which fixes the
issue.
