PostgreSQL circle_poly, path_encode, and path_add functions integer overflows

postgresql-circlepoly-integer-overflow (11080) The risk level is classified as MediumMedium Risk

Description:

PostgreSQL is vulnerable to a denial of service attack, caused by integer overflows in the in circle_poly, path_encode, and path_add functions. A remote attacker could exploit this vulnerability to overflow a buffer and execute arbitrary code on the system or cause the system to crash.


Consequences:
