Description
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.

BinData is a declarative way to read and write binary file formats.
This means the programmer specifies *what* the format of the binary
data is, and BinData works out *how* to read and write data in this
format. It is an easier ( and more readable ) alternative to
ruby's #pack and #unpack methods.
