PostgreSQL regular expressions denial of service

postgresql-regular-expression-dos (39497)

Low Risk

Description:

PostgreSQL is vulnerable to a denial of service, caused by an error when processing regular expressions. By creating infinite loops using regular expressions, a remote attacker could crash the application.
