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.

Affected products

Fedoraproject Fedora: 29, 30
openSUSE Leap: 15.0, 15.1
PostgreSQL: from 10.0 before 10.9; from 11.0 before 11.4 — fixed in 10.9, 11.4
Red Hat Enterprise Linux: 8.0

How to fix

Upgrade to a fixed version: PostgreSQL 10.9, 11.4. Check the vendor advisory for mitigations.
