+Subject: [PATCH] Fix CVE-2022-24795 (from brianmario/yajl-ruby)
+
+The buffer reallocation could cause heap corruption because of `need`
+overflow for large inputs. In addition, there's a possible infinite loop
+in case `need` reaches zero.
+
+The fix is to `abort()` if the loop ends with lower value of `need` than
+when it started.
