Discussion

PostgreSQL path_add() Buffer Overrun Vulnerability

PostgreSQL is prone to a buffer overflow in the path_add() function. The vulnerability is due to insufficient bounds checking of user-supplied data.

Successful exploitation will enable an attacker to execute code in the content of the database server process. A denial of service may also be the result of exploitation attempts.
