Vulnerability GHSA-j7fr-3v8c-3qc3
Summary
sqlite3-ruby has Use-After-Free in SQLite Aggregate Function Callbacks
Details
Summary
Using Database#create_aggregate, #create_aggregate_handler, or Database#define_aggregator to define an aggregate function, and then using an open statement calling that function after the database has been explicitly closed will result in an invalid memory read and a segmentation fault.
Mitigation
Upgrade to sqlite3 gem v2.9.5 or later.
As a workaround, avoid using an aggregate function after closing the database.
Severity
The sqlite3-ruby maintainers assess this as Low severity. It is reliably triggered after GC when code is structured in a particular way. There is no known general exploit that could be used as a denial of service attack.
