И в некоторых местах strdup не проверяется.
Первый же пример grep -C3 strdup **/*.c

extensions/libip6t_ah.c-        char *buffer;
extensions/libip6t_ah.c-        char *cp;
extensions/libip6t_ah.c-
extensions/libip6t_ah.c:        buffer = strdup(spistring);
extensions/libip6t_ah.c-        if ((cp = strchr(buffer, ':')) == NULL)
extensions/libip6t_ah.c-                spis[0] = spis[1] = parse_ah_spi(buffer,"spi");
extensions/libip6t_ah.c-        else {

Специально напрашиваемся на взятие значения по нулевому адресу...

Это в очередной раз доказывает тот факт, что административные утилиты
(типа iptables) написаны так плохо и доверяют клиенту в такой мере, что их
нельзя использовать с входными данными, не проверенными на 100%.
