rh-postgresql94-postgresql-9.4.14-2.el7

PostgreSQL is an advanced object-relational database management system (DBMS).

Security Fix(es):

* 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. (CVE-2017-12172, CVE-2017-15097)

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.

Asianux would like to thank the PostgreSQL project for reporting CVE-2017-12172. The CVE-2017-15097 issue was discovered by Pedro Barbosa (Asianux) and the PostgreSQL project. Upstream acknowledges Antoine Scemama (Brainloop) as the original reporter of these issues.

CVE-2017-12172
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.
