A vulnerability, which was classified as critical, was found in Netgear D6400, D7000v2, D8500, DGN2200v4, DGND2200Bv4, EX3700, EX3800, EX6000, EX6100, EX6120, EX6130, EX6150v1, EX6200, EX7000, R6250, R6300v2, R6400, R6400v2, R6700, R6900, R7000, R6900P, R7000P, R7100LG, R7300DST, R7900, R8000, R7900P, R8000P, R8300, R8500, WN2500RPv2, WNDR3400v3 and WNR3500Lv2 (Wireless LAN Software). This affects some unknown processing. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:
Certain NETGEAR devices are affected by a stack-based buffer overflow by an unauthenticated attacker.
