- OVAL oval_set.c: a <set> mixing a nested <set> (aggregate) with
object_reference/filter children (collective) wrote into the wrong union
member, so oval_setobject_free() later freed a model-owned object
(use-after-free / double free). Reject children that don't match the
established set type.
- XCCDF resolve.c: <warning> entries were resolved through
xccdf_resolve_textlist(), which reads each item as oscap_text -- but a
xccdf_warning is smaller, so this read out of bounds (heap-buffer-overflow).
Added a dedicated xccdf_resolve_warninglist() operating on warning->text.
- DS sds.c: component_id aliased the xlink_href buffer that was freed too
early (use-after-free); keep it alive until last use. Also cap catalog
component-ref recursion (cyclic catalog -> OOM); this recursion-DoS fix is
bundled here because it is interleaved with the UAF fix in the same function.
Also a NULL id guard in lookup_component_in_collection.
- source/schematron.c: OSCAP_SCHEMATRON_TABLE lacked the {0,NULL,NULL}
sentinel its lookup loop relies on -> global-buffer-overflow; added it.
Plus NULL guards for missing href/uri, empty <catalog>, and NULL XPath eval.
