+  date: 2024-02-04
+  description: |
+    ### Summary
+
+    Nokogiri v1.16.2 upgrades the version of its dependency libxml2 to v2.12.5.
+
+    libxml2 v2.12.5 addresses 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 < 1.16.2, 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.
+
+    ### Severity
+
+    The Nokogiri maintainers have evaluated this as **Moderate**.
+
+    ### Mitigation
+
+    Upgrade to Nokogiri >= 1.16.2.
+
+    Users who are unable to upgrade Nokogiri may also choose a more complicated
+    mitigation: compile and link Nokogiri against external libraries libxml2 >=
+    2.12.5 which will also address these same issues.
+
+    JRuby users are not affected.
+
+    ### Workarounds
+  patched_versions:
+  - ">= 1.16.2"
