+Subject: [PATCH 04/18] Avoid dangling ptrs in header and data params for
+ PEM_read_bio_ex
+
+In the event of a failure in PEM_read_bio_ex() we free the buffers we
+allocated for the header and data buffers. However we were not clearing
+the ptrs stored in *header and *data. Since, on success, the caller is
+responsible for freeing these ptrs this can potentially lead to a double
+free if the caller frees them even on failure.
+
+Thanks to Dawei Wang for reporting this issue.
+
+Based on a proposed patch by Kurt Roeckx.

+Subject: [PATCH 05/18] Add a test for CVE-2022-4450
+
+Call PEM_read_bio_ex() and expect a failure. There should be no dangling
+ptrs and therefore there should be no double free if we free the ptrs on
+error.
