Use-after-free in libxml2 via Nokogiri::XML::Reader
Summary
Nokogiri upgrades its dependency libxml2 as follows:
- v1.15.6 upgrades libxml2 to 2.11.7 from 2.11.6
- v1.16.2 upgrades libxml2 to 2.12.5 from 2.12.4
libxml2 v2.11.7 and v2.12.5 address the following vulnerability:
CVE-2024-25062 / https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-25062
- described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/604
- patched by https://gitlab.gnome.org/GNOME/libxml2/-/commit/92721970
Please 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.
JRuby users are not affected.
Severity
The Nokogiri maintainers have evaluated this as Moderate.
Impact
From the CVE description, this issue applies to the xmlTextReader module (which underlies
Nokogiri::XML::Reader):
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.
Mitigation
Upgrade to Nokogiri ~> 1.15.6 or >= 1.16.2.
Users who are unable to upgrade Nokogiri may also choose a more complicated mitigation: compile
and link Nokogiri against patched external libxml2 libraries which will also address these same
issues.
