Descriptions

The postgresql-ocaml bindings 1.5.4, 1.7.0, and 1.12.1 for PostgreSQL libpq do not properly support the PQescapeStringConn function, which might allow remote attackers to leverage escaping issues involving multibyte character encodings.

Los vínculos Postgresql-ocaml v1.5.4, v1.7.0, y v1.12.1 para la librería libpq para PostgreSQL no soporta de forma adecuada la función PQescapeStringConn, lo que podría permitir a atacantes remotos aprovechas cuestiones de escape incluidas en las codificaciones de carácter multibyte.

It was discovered that postgresql-ocaml, OCaml bindings to PostgreSQL's libpq, was missing a function to call PQescapeStringConn(). This is needed, because PQescapeStringConn() honours the charset of the connection and prevents insufficient escaping, when certain multibyte character encodings are used. The added function is called escape_string_conn() and takes the established database connection as a first argument. The old escape_string() was kept for backwards compatibility.
