TITLE

plural NETGEAR Out-of-bounds write vulnerabilities in devices

Trust: 0.8

sources: JVNDB: JVNDB-2019-015392

DESCRIPTION

Certain NETGEAR devices are affected by a stack-based buffer overflow by an unauthenticated attacker. This affects D3600 before 1.0.0.75, D6000 before 1.0.0.75, D6200 before 1.1.00.32, D7000 before 1.0.1.68, JR6150 before 1.0.1.18, PR2000 before 1.0.0.28, R6020 before 1.0.0.38, R6050 before 1.0.1.18, R6080 before 1.0.0.38, R6120 before 1.0.0.46, R6220 before 1.1.0.80, R6260 before 1.1.0.40, R6700v2 before 1.2.0.36, R6800 before 1.2.0.36, R6900v2 before 1.2.0.36, WNR2020 before 1.1.0.62, and XR500 before 2.3.2.32. 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 R6700, 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
