Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-416: Use After Free, where the product reuses or references memory after it has been freed. at some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer. 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.

"details" : "## Summary\n\nNokogiri upgrades its dependency libxml2 as follows:\n- Nokogiri v1.15.6 upgrades libxml2 to [2.11.7](https://gitlab.gnome.org/GNOME/libxml2/-/releases/v2.11.7) from 2.11.6\n- Nokogiri v1.16.2 upgrades libxml2 to [2.12.5](https://gitlab.gnome.org/GNOME/libxml2/-/releases/v2.12.5) from 2.12.4\n\nlibxml2 v2.11.7 and v2.12.5 address the following vulnerability:\n\n- CVE-2024-25062 / https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-25062\n - described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/604\n - patched by https://gitlab.gnome.org/GNOME/libxml2/-/commit/92721970\n\nPlease 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.\n\nJRuby users are not affected.\n\n## Mitigation\n\nUpgrade to Nokogiri `~> 1.15.6` or `>= 1.16.2`.\n\nUsers who are unable to upgrade Nokogiri may also choose a more complicated mitigation: compile\nand link Nokogiri against patched external libxml2 libraries which will also address these same\nissues.\n\n## Impact\n\nFrom the CVE description, this issue applies to the `xmlTextReader` module (which underlies `Nokogiri::XML::Reader`):\n\n> 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.\n\n## Timeline\n\n- 2024-02-04 10:35 EST - this GHSA is drafted without complete details about when the upstream issue was introduced; a request is made of libxml2 maintainers for more detailed information\n- 2024-02-04 10:48 EST - updated GHSA to reflect libxml2 maintainers' confirmation of affected versions\n- 2024-02-04 11:54 EST - v1.16.2 published, this GHSA made public\n- 2024-02-05 10:18 EST - updated with MITRE link to the CVE information, and updated \"Impact\" section\n- 2024-03-16 09:03 EDT - v1.15.6 published (see discussion at https://github.com/sparklemotion/nokogiri/discussions/3146), updated mitigation information\n- 2024-03-18 22:12 EDT - update \"affected products\" range with v1.15.6 information",
