The following vulnerability was published for ruby-bindata.

| In the bindata RubyGem before version 2.4.10 there is a potential
| denial-of-service vulnerability. In affected versions it is very slow
| for certain classes in BinData to be created. For example
| BinData::Bit100000, BinData::Bit100001, BinData::Bit100002,
| BinData::Bit<N>. In combination with
| <user_input>.constantize there is a potential for a CPU-based
| DoS. In version 2.4.10 bindata improved the creation time of Bits and
| Integers.

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
