VUL-1: CVE-2021-32823: rubygem-bindata: In version before 2.4.10 there is a potential denial-of-service vulnerability.
Last modified: 2021-06-24 17:24:42 UTC
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.
