Ensure extension directory has appropriate ownership and permissions

높음레벨 1자동postgres

설명

The extension directory is the location of the PostgreSQL extensions. Extensions are storage engines or user defined functions (UDFs). Reads SHAREDIR from the pg_config view (superuser) and requires <sharedir>/extension to be drwxr-xr-x root:root. Runs psql as ${PGUSER:-postgres} against ${PGDATABASE:-postgres}; set PGHOST/PGPORT and use ~/.pgpass (not PGPASSWORD, see 1.6/1.7) when peer authentication is not available.

점검 방법

감사 방식: 셸 명령

shell

sd=$(psql -X -U "${PGUSER:-postgres}" -d "${PGDATABASE:-postgres}" -tAc "SELECT setting FROM pg_config WHERE name = 'SHAREDIR'" 2>/dev/null) || exit 1; [ -n "$sd" ] || exit 1; s=$(stat -c '%a %U %G' "$sd/extension" 2>/dev/null) || exit 1; [ "$s" = "755 root root" ] && echo compliant || echo "$s"

예상 출력: compliant

조치 방법

조치 방식: 가이드 또는 인프라 패치

chown root:root <sharedir>/extension && chmod 0755 <sharedir>/extension (sharedir from pg_config --sharedir). If the permissions needed correcting, verify that no extension files in that directory were modified.
