Potential Denial-of-Service in bindata(CVE-2021-32823)

概要

Potential Denial-of-Service in bindata

原文の説明

取得元が公開している説明をそのまま載せています (多くは英語)。

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. In combination with .constantize there is a potential for a CPU-based DoS. In version 2.4.10 bindata improved the creation time of Bits and Integers.
