The T1/E1 driver-queue functionality in Cisco IOS 12.2 and 15.0 through 15.3, when an HDLC32 driver is used, allows remote attackers to cause a denial of service (interface queue wedge) via bursty network traffic, aka Bug ID CSCub67465. Cisco IOS of T1/E1 driver-queue Features include HDLC32 If you are using a driver, the service operation is interrupted. ( Interface queue wedge ) There are vulnerabilities that are put into a state. Cisco IOS is the interconnected network operating system used on most Cisco system routers and network switches. When the affected device handles burst communication, the packets queued by the Cisco IOS router or switch are not deleted from the queue, which can cause an interface queue attack. Repeated exploitation can lead to denial of service attacks. The following devices are affected by this vulnerability: Cisco IOS15.0(1)M1 Base | 15.0M 15.0(1)M, 15.0(1)M10, 15.0(1)M2, 15.0(1)M3, 15.0(1)M4, 15.0( 1) M5, 15.0(1)M6, 15.0(1)M6a, 15.0(1)M7, 15.0(1)M8, 15.0(1)M9 | 15.0XA 15.0(1)XA, 15.0(1)XA1, 15.0( 1) XA2, 15.0(1)XA3, 15.0(1)XA4, 15.0(1)XA5 | 15.1(2)T Base | 15.1GC 15.1(2)GC, 15.1(2)GC1, 15.1(2)GC2, 15.1 (4)GC, 15.1(4)GC1 | 15.1M 15.1(4)M, 15.1(4)M0a, 15.1(4)M0b, 15.1(4)M1, 15.1(4)M2, 15.1(4)M3, 15.1 (4) M3a, 15.1(4)M4, 15.1(4)M5, 15.1(4)M6 | 15.1T 15.1(1)T, 15.1(1)T1, 15.1(1)T2, 15.1(1)T3, 15.1 (1) T4, 15.1(1)T5, 15.1(2)T0a, 15.1(2)T1, 15.1(2)T2, 15.1(2)T2a, 15.1(2)T3, 15.1(2)T4, 15.1(2 ) T5, 15.1(3)T, 15.1(3)T1, 15.1(3)T2, 15.1(3)T3, 15.1(3)T4…
