Cisco IOS is the interconnected network operating system used on most Cisco system routers and network switches. When PPTP packets are not processed correctly when converting packets on the NAT boundary, unauthenticated remote attackers can exploit the vulnerability to overload the device. An unauthenticated remote attacker can repeatedly send some legitimate PPTP packets to the target device. When the affected device handles malicious communication, the race condition can cause a backtracking or cause the device to terminate the operation incorrectly, resulting in a denial of service attack. The following devices are affected by this vulnerability: Cisco IOS 12.2 SXI 12.2(33) SXI7 | 12.2SXJ 12.2(33)SXJ1 | 12.2SY 12.2(50)SY3, 12.2(50)SY4 | 15.0M 15.0(1)M6, 15.0(1) M6a, 15.0(1)M7 | 15.0SY 15.0(1)SY | 15.1M 15.1(4)M1 | 15.1T 15.1(2)T4 | 15.1XB 15.1(4)XB5, 15.1(4)XB5a | 15.2GC 15.2( 1) GC, 15.2(1)GC1, 15.2(1)GC2 | 15.2T 15.2(1)T, 15.2(1)T1, 15.2(1)T2.
