GLSA-201810-08 : PostgreSQL: Multiple vulnerabilities

Medium Nessus Plugin ID 118508

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-201810-08 (PostgreSQL: Multiple vulnerabilities)

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.

Solution

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'
