Descriptions

An issue was discovered in Suricata 4.1.4. By sending multiple IPv4 packets that have invalid IPv4Options, the function IPV4OptValidateTimestamp in decode-ipv4.c tries to access a memory region that is not allocated. There is a check for o->len < 5 (corresponding to 2 bytes of header and 3 bytes of data). Then, "flag = *(o->data + 3)" places one beyond the 3 bytes, because the code should have been "flag = *(o->data + 1)" instead.

Se detectó un problema en Suricata versión 4.1.4. Mediante el envío de múltiples paquetes IPv4 que tienen IPv4Options no válidas, la función IPV4OptValidateTimestamp en el archivo decode-ipv4.c, intenta acceder a una región de memoria que no está asignada. Se presenta una comprobación para o-)len( 5 (correspondiente a 2 bytes de encabezado y 3 bytes de datos). Luego, "flag = *(o-)data + 3)" se coloca uno más allá de los 3 bytes, porque en su lugar el código debería haber sido "flag = *(o-)data + 1)".
