Description

Nokogiri updates packaged libxml2 to v2.13.8 to resolve CVE-2025-32414 and CVE-2025-32415

Summary

Nokogiri v1.18.8 upgrades its dependency libxml2 to [v2.13.8](https://gitlab.gnome.org/GNOME/libxml2/-/releases/v2.13.8).

libxml2 v2.13.8 addresses:

  • CVE-2025-32414
  • described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/889
  • CVE-2025-32415
  • described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/890

Impact

CVE-2025-32414: No impact

In libxml2 before 2.13.8 and 2.14.x before 2.14.2, out-of-bounds memory access can occur in the Python API (Python bindings) because of an incorrect return value. This occurs in xmlPythonFileRead and xmlPythonFileReadRaw because of a difference between bytes and characters.

There is no impact from this CVE for Nokogiri users.

CVE-2025-32415: Low impact

In libxml2 before 2.13.8 and 2.14.x before 2.14.2, xmlSchemaIDCFillNodeTables in xmlschemas.c has a heap-based buffer under-read. To exploit this, a crafted XML document must be validated against an XML schema with certain identity constraints, or a crafted XML schema must be used.

In the upstream issue, further context is provided by the maintainer:

> The bug affects validation against untrusted XML Schemas (.xsd) and 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.
