Ensure extension directory has appropriate ownership and permissions

TinggiLevel 1Otomatispostgres

Deskripsi

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.

Cara pemeriksaan

Metode audit: Perintah shell

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"

Output yang diharapkan: compliant

Cara perbaikan

Metode perbaikan: Panduan atau patch infrastruktur

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.
