+Subject: [PATCH] rar: Fix double free with over 4 billion nodes (#2598)
+
+If a system is capable of handling 4 billion nodes in memory, a double
+free could occur because of an unsigned integer overflow leading to a
+realloc call with size argument of 0. Eventually, the client will
+release that memory again, triggering a double free.
