Summary: Invalid free of connection pointer
Description:
This may or may not cause a crash, but invalid memory is being accessed on
failure to connect to the PGSQL database.
Specifically -
lines 88-92:
pgerror = PQerrorMessage(conn);
PQfinish(conn);
ast_log(LOG_ERROR, "cdr_pgsql: Unable to connect to database server %s.
Calls will not be logged!\n", pghostname);
ast_log(LOG_ERROR, "cdr_pgsql: Reason: %s\n", pgerror);
---------------
PQfinish should come after line 92, because pgerror is a pointer to one of
the fields in conn:
pgerror = PQerrorMessage(conn);
ast_log(LOG_ERROR, "cdr_pgsql: Unable to connect to database server %s.
Calls will not be logged!\n", pghostname);
ast_log(LOG_ERROR, "cdr_pgsql: Reason: %s\n", pgerror);
PQfinish(conn);
---------------
The same goes for lines 148-152. It should be:
pgerror = PQerrorMessage(conn);
ast_log(LOG_ERROR, "cdr_pgsql: Unable to reconnect to database server
%s. Calls will not be logged!\n", pghostname);
ast_log(LOG_ERROR, "cdr_pgsql: Reason: %s\n", pgerror);
PQfinish(conn);
