CVE-2017-12172

Status Candidate

Overview

PostgreSQL 10.x before 10.1, 9.6.x before 9.6.6, 9.5.x before 9.5.10, 9.4.x before 9.4.15, 9.3.x before 9.3.20, and 9.2.x before 9.2.24 runs under a non-root operating system account, and database superusers have effective ability to run arbitrary code under that system account. PostgreSQL provides a script for starting the database server during system boot. Packages of PostgreSQL for many operating systems provide their own, packager-authored startup implementations. Several implementations use a log file name that the database superuser can replace with a symbolic link. As root, they open(), chmod() and/or chown() this log file name. This often suffices for the database superuser to escalate to root privileges when root starts the server.

Red Hat Security Advisory 2017-3405-01 - PostgreSQL is an advanced object-relational database management system. Security Fix: Privilege escalation flaws were found in the initialization scripts of PostgreSQL. An attacker with access to the postgres user account could use these flaws to obtain root access on the server machine. Note: This patch drops the script privileges from root to the postgres user. Therefore, we dropped the --new-systemd-unit option for security reasons. Please use the root-only script postgresql-new-systemd-unit.

Red Hat Security Advisory 2017-3402-01 - PostgreSQL is an advanced object-relational database management system. Security Fix: Privilege escalation flaws were found in the initialization scripts of PostgreSQL. An attacker with access to the postgres user account could use these flaws to obtain root access on the server machine. Note: This patch drops the script privileges from root to the postgres user. Therefore, this update works properly only if the postgres user has write access to the postgres' home directory, such as the one in the default configuration.
