Descriptions
In SQLite 3.31.1, isAuxiliaryVtabOperator allows attackers to trigger a NULL pointer dereference and segmentation fault because of generated column optimizations.
En SQLite versión 3.31.1, la función isAuxiliaryVtabOperator permite a atacantes desencadenar una desreferencia del puntero NULL y un fallo de segmentación debido a las optimizaciones de columna generadas.
A NULL pointer dereference was found in SQLite in the way it executes select statements with column optimizations. An attacker who is able to execute SQL statements can use this flaw to crash the application.
SQLite is a C library that implements an SQL database engine. A large subset of SQL92 is supported. A complete database is stored in a single disk file. The API is designed for convenience and ease of use. Applications that link against SQLite can enjoy the power and flexibility of an SQL database without the administrative hassles of supporting a separate database server. Issues addressed include code execution, null pointer, out of bounds read, and use-after-free vulnerabilities.
