Use-After-Free in SQLite Database Engine

Executive Summary

This is a use-after-free vulnerability in SQLite 3.41. It occurs when the jsonBlobAppendNode() function is called after sqlite3DbFree() has already freed the aBlob member of the Parse structure. This means the program tries to use memory that has already been released, which can lead to crashes or arbitrary code execution.
