CVE-2019-10164
PostgreSQL versions 10.x before 10.9 and versions 11.x before 11.4 are vulnerable to a stack-based buffer overflow.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.64%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
PostgreSQL versions 10.x before 10.9 and versions 11.x before 11.4 are vulnerable to a stack-based buffer overflow. Any authenticated user can overflow a stack-based buffer by changing the user's own password to a purpose-crafted value. This often suffices to execute arbitrary code as the PostgreSQL operating system account.
