This link is maintained to preserve external references. # Original Description ## Summary Nokogiri v1.18.3 upgrades its dependency libxml2 to [v2.13.6](https://gitlab.gnome.org/GNOME/libxml2/-/releases/v2.13.6). libxml2 v2.13.6 addresses: - CVE-2025-24928 - described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/847 - CVE-2024-56171 - described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/828 ## Impact ### CVE-2025-24928 Stack-buffer overflow is possible when reporting DTD validation errors if the input contains a long (~3kb) QName prefix. ### CVE-2024-56171 Use-after-free is possible during validation against untrusted XML Schemas (.xsd) and, potentially, validation of untrusted documents against trusted Schemas if they make use of `xsd:keyref` in combination with recursively defined types that have additional identity constraints.
