Descriptions

SQLite before 3.25.3, when the FTS3 extension is enabled, encounters an integer overflow (and resultant buffer overflow) for FTS3 queries that occur after crafted changes to FTS3 shadow tables, allowing remote attackers to execute arbitrary code by leveraging the ability to run arbitrary SQL statements (such as in certain WebSQL use cases), aka Magellan.

SQLite anterior a la versión 3.25.3, cuando la extensión FTS3 está habilitada, encuentra un desbordamiento de enteros (y el desbordamiento del búfer resultante) para las consultas FTS3 que ocurren después de los cambios especialmente diseñados en las tablas de sombra FTS3, lo que permite a los atacantes remotos ejecutar código arbitrario aprovechando la capacidad de ejecutar arbitrariamente Sentencias SQL (como en ciertos casos de uso de WebSQL), también conocido como Magellan.
