Summary
[none]
Details

A NULL pointer dereference in the SQLite Session Extension in SQLite 3.53.1 and SQLite trunk builds before check-in e807d4e3798efd53 allows an attacker who can supply a malformed changeset blob to cause a denial of service. The issue occurs when sqlite3changesetapplyv3() applies a corrupt changeset and reaches sqlite3valuetype() with a NULL sqlite3_value pointer.
