| Summary | Use-after-free in libxml2 via Nokogiri::XML::Reader ### Summary Nokogiri upgrades its dependency libxml2 as follows: - v1.15.6 upgrades libxml2 to 2.11.7 from 2.11.6 - v1.16.2 upgrades libxml2 to 2.12.5 from 2.12.4 libxml2 v2.11.7 and v2.12.5 address the following vulnerability: CVE-2024-25062 / https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-25062 - described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/604 - patched by https://gitlab.gnome.org/GNOME/libxml2/-/commit/92721970 Please note that this advisory only applies to the CRuby implementation of Nokogiri, and only if the packaged libraries are being used. If you've overridden defaults at installation time to use system libraries instead of packaged libraries, you should instead pay attention to your distro's libxml2 release announcements. JRuby users are not affected. ### Severity The Nokogiri maintainers have evaluated this as **Moderate**. ### Impact From the CVE description, this issue applies to the `xmlTextReader` module (which underlies `Nokogiri::XML::Reader`): > When using the XML Reader interface with DTD validation and XInclude expansion enabled, > processing crafted XML documents can lead to an xmlValidatePopElement use-after-free. ### Mitigation Upgrade to Nokogiri `~> 1.15.6` or `>= 1.16.2`. Users who are unable to upgrade Nokogiri may also choose a more complicated mitigation: compile and link Nokogiri against patched external libxml2 libraries which will also address these same issues. |
