libxml2: Fix CVE-2021-3518
This patch fixes CVE-2021-3518. The fix for the CVE is the
following 3 lines in
1098c30a:
- (cur->children->type != XML_ENTITY_DECL) &&
- (cur->children->type != XML_XINCLUDE_START) &&
- (cur->children->type != XML_XINCLUDE_END)) {
+ ((cur->type == XML_DOCUMENT_NODE) ||
+ (cur->type == XML_ELEMENT_NODE))) {
This relies on an updated version of xinclude.c from upstream which
also adds several new tests. Those changes are brought in first so
that the CVE patch can be applied cleanly.
The first patch updates xinclude.c and adds the new tests from
upstream, and the second applies the fix for the CVE.
