PostgreSQL postmaster connection request denial of service
|postgresql-connection-request-dos (24049)||Medium Risk|
PostgreSQL is vulnerable to a denial of service attack. A remote attacker could send multiple simultaneous requests to cause the postmaster to exit, preventing any new database connections. The postmaster must be manually restarted to regain normal functionality.
Denial of Service
Upgrade to the latest version of PostgreSQL (8.1.2 or 8.0.6 or later), available from the PostgreSQL Web site. See References.
