sqlite3-ruby has Use-After-Free When Redefining SQLite Functions with Different Arity

NVD Description

## 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.
