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.","state":0,"publishedAt":"2017-11-22T19:00:00+00:00","modifiedAt":"2026-10-15T15:51:56.38+00:00","affected":[{"ecosystem":"Vendor product","name":"postgresql","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"postgresql\",\n                    \"vendor\": \"Red Hat, Inc.\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"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, 9.2.x before 9.2.24\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://access.redhat.com/errata/RHSA-2017:3402","http://www.securityfocus.com/bid/101949","https://access.redhat.com/errata/RHSA-2017:3403","https://access.redhat.com/errata/RHSA-2017:3405","https://www.postgresql.org/support/security/","http://www.securitytracker.com/id/1039752","https://www.postgresql.org/about/news/1801/","https://access.redhat.com/errata/RHSA-2017:3404"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2017-12172","license":"CVE Program Terms of Use","key":"cve-program:CVE-2017-12172","identifiers":["CVE-2017-12172"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
