CVE-2017-7548
PostgreSQL versions before 9.4.13, 9.5.8 and 9.6.4 are vulnerable to authorization flaw allowing remote authenticated attackers with no privileges on a large object to overwrite the entire contents of the object, resulting in a denial of service.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.52%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
