Details

Summary

Nokogiri v1.18.3 upgrades its dependency libxml2 to 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.
