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.
