The flaw resides in the libpq client library and can be triggered when a client receives specially crafted PostgreSQL protocol data that causes an integer wraparound and an out-of-bounds write. The attack complexity is Low because the malformed protocol message is processed immediately during connection, with no timing or environmental conditions required. However, the impact is limited to a denial of service of the client application only. As a result, Red Hat classifies the overall product impact as Moderate, reflecting that the flaw can interrupt client availability.",
