+Subject: [PATCH 1/2] subparse: Look for the closing `>` of a tag after the
+ opening `<`
+
+Previously when fixing up subrip markip, we were looking from the start
+of the remaining buffer instead. Due to how skipping over closing tags
+works, the remaining buffer will still contain the closing `>` of the
+previous tag so if a unexpected closing tag is found after another
+closing tag, we would potentially do an out of bounds memmove().
+
+Fixes ZDI-CAN-20968
+Fixes https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/2662

+Subject: [PATCH 2/2] subparse: Skip after the end of a valid closing tag
+ instead of only skipping `<`
+
+This is a small optimization and avoids restarting the next parsing
+iteration on already accepted data.
+
+On its own it would also fix ZDI-CAN-20968 (see previous commit) but the
+previous commit independently is also a valid fix for it.
