+Subject: [PATCH 2/4] Sanitize libxml2 globals before parsing
+
+Fixes GHSA-3qrf-m4j2-pcrr.
+
+To parse a document with libxml2, you first need to create a parsing context.
+The parsing context contains parsing options (e.g. XML_NOENT to substitute
+entities) that the application (in this case PHP) can set.
+Unfortunately, libxml2 also supports providing default set options.
+For example, if you call xmlSubstituteEntitiesDefault(1) then the XML_NOENT
+option will be added to the parsing options every time you create a parsing
+context **even if the application never requested XML_NOENT**.
+
+Third party extensions can override these globals, in particular the
+substitute entity global. This causes entity substitution to be
+unexpectedly active.
+
+Fix it by setting the parsing options to a sane known value.
+For API calls that depend on global state we introduce
+PHP_LIBXML_SANITIZE_GLOBALS() and PHP_LIBXML_RESTORE_GLOBALS().
+For other APIs that work directly with a context we introduce
+php_libxml_sanitize_parse_ctxt_options().
+
