+Subject: [PATCH 2/3] Fix #81726: phar wrapper: DOS when using quine gzip file
+
+The phar wrapper needs to uncompress the file; the uncompressed file
+might be compressed, so the wrapper implementation loops. This raises
+potential DOS issues regarding too deep or even infinite recursion (the
+latter are called compressed file quines[1]). We avoid that by
+introducing a recursion limit; we choose the somewhat arbitrary limit
+`3`.
+
+This issue has been reported by real_as3617 and gPayl0ad.

+Subject: [PATCH 3/3] Fix regression introduced by fixing bug 81726
+
+When a tar phar is created, `phar_open_from_fp()` is also called, but
+since the file has just been created, none of the format checks can
+succeed, so we continue to loop, but must not check again for the
+format.  Therefore, we bring back the old `test` variable.
+
+Closes GH-9620.
