The vulnerabilities of the negotiation mechanisms for SSL and GSS in the PostgreSQL database management system allow attackers to induce service failures.

The vulnerability of the negotiation mechanisms for SSL and GSS in the PostgreSQL database management system is related to an uncontrolled recursion. Exploiting this vulnerability can allow a malicious actor, operating remotely, to cause service interruptions...

BIT-POSTGRESQL-2026-6479 PostgreSQL SSL/GSS init causes denial of service, via uncontrolled recursion

Uncontrolled recursion in PostgreSQL SSL and GSS negotiation allows an attacker able to connect to a PostgreSQL AFUNIX socket to achieve sustained denial of service. If SSL and GSS are both disabled, an attacker can do the same via access to a PostgreSQL TCP socket. Versions before PostgreSQL 18....

Uncontrolled Recursion

Overview Affected versions of this package are vulnerable to Uncontrolled Recursion through the SSL or GSS negotiation process. An attacker can cause the service to become unresponsive by triggering uncontrolled recursion when connecting to an AFUNIX socket. If both SSL and GSS are disabled, the...
