Descriptions

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.

En bindata RubyGem versiones anteriores a 2.4.10, presenta una vulnerabilidad potencial de denegación de servicio.&#xa0;En las versiones afectadas, es muy lento crear determinadas clases en BinData.&#xa0;Por ejemplo,BinData::Bit100000, BinData::Bit100001, BinData::Bit100002, BinData::Bit(N).&#xa0;En combinación con (user_input) .constantize, se presenta la posibilidad de un DoS basado en CPU.&#xa0;En la versión 2.4.10 bindata mejoró el tiempo de creación de Bits e Integers
