Severity:	high
Title:	PostgreSQL: Multiple vulnerabilities
Date:	10/30/2018
Bugs:	#603716, #603720, #664332
ID:	201810-08

Synopsis

Multiple vulnerabilities have been found in PostgreSQL, the worst which could lead to privilege escalation.

Background

PostgreSQL is an open source object-relational database management system.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
dev-db/postgresql	< 10.5	>= 9.3.24	All supported architectures

Description

Multiple vulnerabilities have been discovered in PostgreSQL. Please review the referenced CVE identifiers for details.

In addition it was discovered that Gentoo’s PostgreSQL installation suffered from a privilege escalation vulnerability due to a runscript which called OpenRC’s checkpath() on a user controlled path and allowed user running PostgreSQL to kill arbitrary processes via PID file manipulation.

Impact

A remote attacker could bypass certain client-side connection security features, read arbitrary server memory or alter certain data.

In addition, a local attacker could gain privileges or cause a Denial of Service condition by killing arbitrary processes.

Workaround

There is no known workaround at this time.

Resolution

All PostgreSQL users up to 9.3 should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-db/postgresql-9.3.24:9.3"

All PostgreSQL 9.4 users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-db/postgresql-9.4.19:9.4"

All PostgreSQL 9.5 users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-db/postgresql-9.5.14:9.5"

All PostgreSQL 9.6 users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-db/postgresql-9.6.10:9.6"

All PostgreSQL 10 users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-db/postgresql-10.5:10"
