Certain NETGEAR devices are affected by a buffer overflow by an unauthenticated attacker. This affects D6220 before 1.0.0.40, D8500 before 1.0.3.39, EX3700 before 1.0.0.70, EX3800 before 1.0.0.70, EX6000 before 1.0.0.30, EX6100 before 1.0.2.22, EX6120 before 1.0.0.40, EX6130 before 1.0.0.22, EX6150v1 before 1.0.0.42, EX6200 before 1.0.3.88, EX7000 before 1.0.0.66, R6300v2 before 1.0.4.18, R6400 before 1.0.1.24, R6400v2 before 1.0.2.32, R6700 before 1.0.1.22, R6700v3 before 1.0.2.32, R6900 before 1.0.1.22, R7000 before 1.0.9.6, R6900P before 1.0.0.56, R7000P before 1.0.0.56, R7100LG before 1.0.0.42, R7300DST before 1.0.0.54, R7900 before 1.0.1.26, R8300 before 1.0.2.106, R8500 before 1.0.2.106, WN2500RPv2 before 1.0.1.54, and WNR3500Lv2 before 1.2.0.46. NOTE: this may be a result of an incomplete fix for CVE-2017-18864. plural NETGEAR A classic buffer overflow vulnerability exists on the device.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. NETGEAR D6220, etc. are all products of NETGEAR. NETGEAR D6220 is a wireless modem. NETGEAR R6300 is a wireless router. NETGEAR EX3700 is a wireless network signal extender. The vulnerability stems from the fact that when the network system or product performs operations on the memory, the data boundary is not correctly verified, resulting in incorrect read and write operations to other associated memory locations. This affects D6220 prior to 1.0.0.40, D8500 prior to 1.0.3.39, EX3700 prior to 1.0.0.70, EX3800 prior to 1.0.0.70, EX6000 prior to 1.0.0.30, EX6100 prior to 1.0.2.22, EX6120 prior to 1.0.0.40, EX6130 prior to 1.0.0.22, EX6150v1 prior to 1.0.0.42, EX6200 prior to 1.0.3.88, EX7000 prior to 1.0.0.66, R6300v2 prior to 1.0.4.18, R6400 prior to 1.0.1.24, R6400v2 prior to 1.0.2.32, R6700 prior to 1.0.1.22, R6700v3 prior to 1.0.2.32, R6900 prior to 1.0.1.22, R7000 prior to 1.0.9.6, R6900P prior to 1.0.0.56, R7000P prior to 1.0.0.56, R7100LG prior to 1.0.0.42, R7300DST prior to 1.0.0.54, R7900 prior to 1.0.1.26, R8300 prior to 1.0.2.106, R8500 prior to 1.0.2.106, WN2500RPv2 prior to 1.0.1.54, and WNR3500Lv2 prior to 1.2.0.46
