Vulnerability Details
CVEID: CVE-2018-10915
DESCRIPTION: PostgreSQL could allow a remote attacker to bypass security
restrictions, caused by an issue with improperly resting internal state in
between connections in the libpq library. By sending a specially-crafted
request, an attacker could exploit this vulnerability to bypass client-side
connection security features.
