Summary

sqlite3 provides Ruby bindings for the SQLite3 embedded database. Prior to 2.10.2, sqlite3-ruby casts Ruby string lengths to int before passing SQL through Database#prepare, bound String or Blob values through Statement#bind_param, and String or Blob results from Ruby-defined SQL functions and aggregates through Database#create_function and Database#create_aggregate. On 64-bit platforms, a string of 4 GiB (2^32 bytes) or larger can wrap the length so SQLite processes only a prefix. A truncated SQL string can drop trailing clauses such as a WHERE condition, while a truncated bound value matters only when the application validated the full value before binding it. Exploitation requires the application and server to accept and retain the unusually large attacker-controlled string. If a dropped SQL clause contained a bind placeholder, binding raises SQLite3::RangeException instead of running the query. This issue is fixed in version 2.10.2.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

The maintainers of sparklemotion/sqlite3-ruby published their own advisory on GitHub. Reviewed sources take precedence over it.
