sqlite3

Summary

Using Database#create_aggregate, #create_aggregate_handler, or Database#define_aggregator to define an aggregate function that takes two or more arguments, and then evaluating it over TEXT or BLOB column values, can free the Ruby objects holding those arguments while a later argument is still being converted, during ordinary garbage collection. The aggregate's step method then receives an incorrect object, or the process crashes with a segmentation fault.

Mitigation

Upgrade to sqlite3 gem v2.9.6 or later.

There is no reliable workaround. If you cannot upgrade, avoid defining aggregate functions that take two or more arguments. Restricting column value sizes is not a mitigation: smaller values make the defect fire less often but do not prevent it.

Severity

The sqlite3-ruby maintainers assess this as Medium severity (CVSS 4.0 score 6.3). It is reached through ordinary garbage collection without any unusual code structuring: an application is exposed whenever it evaluates a multi-argument aggregate over TEXT or BLOB values whose size an attacker can influence. The demonstrated impact is an incorrect value passed to the aggregate's step method, or a process crash; no controlled memory write or general denial-of-service exploit has been demonstrated.

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.

Summary

Using Database#create_function or Database#define_function to define the same function name more than once with different numbers of arguments ("arity") or text encodings will result in a invalid memory read and a segmentation fault.

Mitigation

Upgrade to sqlite3 gem v2.9.5 or later.

As a workaround, avoid defining multiple custom functions with the same name (varying numbers of arguments or encoding).

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.

Summary

Using Database#create_function or Database#define_function to define the same function name more than once with different numbers of arguments ("arity") or text encodings will result in a invalid memory read and a segmentation fault.

Mitigation

Upgrade to sqlite3 gem v2.9.5 or later.

As a workaround, avoid defining multiple custom functions with the same name (varying numbers of arguments or encoding).

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.

Summary

Using Database#create_aggregate, #create_aggregate_handler, or Database#define_aggregator to define an aggregate function that takes two or more arguments, and then evaluating it over TEXT or BLOB column values, can free the Ruby objects holding those arguments while a later argument is still being converted, during ordinary garbage collection. The aggregate's step method then receives an incorrect object, or the process crashes with a segmentation fault.

Mitigation

Upgrade to sqlite3 gem v2.9.6 or later.

There is no reliable workaround. If you cannot upgrade, avoid defining aggregate functions that take two or more arguments. Restricting column value sizes is not a mitigation: smaller values make the defect fire less often but do not prevent it.

Severity

The sqlite3-ruby maintainers assess this as Medium severity (CVSS 4.0 score 6.3). It is reached through ordinary garbage collection without any unusual code structuring: an application is exposed whenever it evaluates a multi-argument aggregate over TEXT or BLOB values whose size an attacker can influence. The demonstrated impact is an incorrect value passed to the aggregate's step method, or a process crash; no controlled memory write or general denial-of-service exploit has been demonstrated.

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.
