CVE-2021-32823 – Potential Denial-of-Service in bindata

https://notcve.org/view.php?id=CVE-2021-32823

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. • https://about.gitlab.com/releases/2021/06/01/security-release-gitlab-13-12-2-released/#update-bindata-dependency https://github.com/dmendel/bindata/blob/v2.4.10/ChangeLog.rdoc#version-2410-2021-05-18- https://github.com/dmendel/bindata/commit/d99f050b88337559be2cb35906c1f8da49531323 https://github.com/rubysec/ruby-advisory-db/issues/476 https://rubygems.org/gems/bindata • CWE-400: Uncontrolled Resource Consumption •
