CVE-2022-23476
Good to know:
Date: December 7, 2022
Nokogiri is an open source XML and HTML library for the Ruby programming language. Nokogiri "1.13.8" and "1.13.9" fail to check the return value from "xmlTextReaderExpand" in the method "Nokogiri::XML::Reader#attribute_hash". This can lead to a null pointer exception when invalid markup is being parsed. For applications using "XML::Reader" to parse untrusted inputs, this may potentially be a vector for a denial of service attack. Users are advised to upgrade to Nokogiri ">= 1.13.10". Users may be able to search their code for calls to either "XML::Reader#attributes" or "XML::Reader#attribute_hash" to determine if they are affected.
