SIPLUS variants), SINAMICS G130, SINAMICS G150, SINAMICS S110, SINAMICS S120 (incl. SIPLUS variants), SINAMICS S150, SINAMICS S210, SINAMICS V90, SIPLUS ET 200S IM151-8 PN/DP CPU, SIPLUS ET 200S IM151-8F PN/DP CPU, SIPLUS HCS4200 CIM4210, SIPLUS HCS4200 CIM4210C, SIPLUS HCS4300 CIM4310, SIPLUS NET PN/PN Coupler, SIPLUS S7-300 CPU 314C-2 PN/DP, SIPLUS S7-300 CPU 315-2 PN/DP, SIPLUS S7-300 CPU 315F-2 PN/DP, SIPLUS S7-300 CPU 317-2 PN/DP, SIPLUS S7-300 CPU 317F-2 PN/DP. The PROFINET (PNIO) stack, when integrated with the Interniche IP stack, improperly handles internal resources for TCP segments where the minimum TCP-Header length is less than defined. This could allow an attacker to create a denial of service condition for TCP services on affected devices by sending specially crafted TCP segments.
