Certain NETGEAR devices are affected by a stack-based buffer overflow by an unauthenticated attacker. This affects DGN2200v1 before 1.0.0.58, D8500 before 1.0.3.42, D7000v2 before 1.0.0.51, D6400 before 1.0.0.78, D6220 before 1.0.0.44, JNDR3000 before 1.0.0.24, R8000 before 1.0.4.18, R8500 before 1.0.2.122, R8300 before 1.0.2.122, R7900 before 1.0.2.16, R7000P before 1.3.2.34, R7300DST before 1.0.0.68, R7100LG before 1.0.0.46, R6900P before 1.3.2.34, R7000 before 1.0.9.28, R6900 before 1.0.1.46, R6700 before 1.0.1.46, R6400v2 before 1.0.2.56, R6400 before 1.0.1.42, R6300v2 before 1.0.4.28, R6250 before 1.0.4.26, WNDR3400v3 before 1.0.1.22, WNDR4500v2 before 1.0.0.72, and WNR3500Lv2 before 1.2.0.50. plural NETGEAR The device is vulnerable to out-of-bounds writes.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. NETGEAR D8500, etc. are all wireless routers from NETGEAR. 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. Attackers can use this vulnerability to cause buffer overflow or heap overflow
