GSD-2021-32823

Vulnerability from gsd - Updated: 2021-05-18 00:00
Details
In bindata 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.
