Title:	PostgreSQL Privilege Escalation Vulnerability (Dec 2017) - Linux
Summary:	PostgreSQL is prone to a privilege escalation vulnerability.
Description:	Summary: PostgreSQL is prone to a privilege escalation vulnerability. Vulnerability Insight: The flaw exists as PostgreSQL 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. Vulnerability Impact: Successful exploitation will allow a local user to modify files on the target system. Affected Software/OS: PostgreSQL version 9.2.x before 9.2.24, 9.3.x before 9.3.20, 9.4.x before 9.4.15, 9.5.x before 9.5.10, 9.6.x before 9.6.6 and 10.x before 10.1. Solution: Upgrade to PostgreSQL version 10.1 or 9.6.6 or 9.5.10 or 9.4.15 or 9.3.20 or 9.2.24 or later. CVSS Score: 7.2 CVSS Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C
