Name of the Vulnerable Software and Affected Versions sqlite3 versions 2.1.0 through 2.9.4

Description Callbacks used for SQLite aggregate functions can be freed while still referenced during aggregation, leading to a use-after-free condition. This occurs when an open statement calling an aggregate function is used after the database has been explicitly closed, resulting in an invalid memory read and a segmentation fault. This issue can be triggered via Database#create aggregate, #create aggregate handler, or Database#define aggregator.

Recommendations Update to version 2.9.5 or later. As a temporary workaround, avoid using an aggregate function after closing the database.
