TMA-POSTGRES-2.2

Ensure extension directory has appropriate ownership and permissions

AltaNível 1Automatizadapostgres

Descrição

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.

Como é verificado

Método de auditoria: Comando 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"

Saída esperada: compliant

Como é corrigido

Método de correção: Orientação ou patch de infraestrutura

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.
