Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-121: Stack-based Buffer Overflow, where a stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). In Nokogiri, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## 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.
