## Overview

SQLite before 3.54.0 built with the session extension contains a heap buffer overflow vulnerability in sqlite3changeset_apply() that allows attackers to corrupt heap memory by supplying crafted changesets. Attackers can repeat a table name in a second changeset block with a larger column count, causing sessionUpdateFind() to memset past the undersized aUpdateMask allocation.

## Affected

- `SQLite < 3.54.0`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
