VAR-202102-0234

Vulnerability from variot - Updated: 2023-12-18 14:00

The function ClientEAPOLKeyRecvd() in the Realtek RTL8195A Wi-Fi Module prior to versions released in April 2020 (up to and excluding 2.08) does not validate the size parameter for an rtl_memcpy() operation, resulting in a stack buffer overflow which can be exploited for denial of service. An attacker can impersonate an Access Point and attack a vulnerable Wi-Fi client, by injecting a crafted packet into the WPA2 handshake. The attacker does not need to know the network's PSK. Realtek RTL8195A Wi-Fi The module contains a vulnerability related to out-of-bounds writing.Denial of service (DoS) It may be put into a state. Realtek RTL8195A is an IoT microcontroller from Taiwan Realtek Semiconductor (Realtek).

Realtek RTL8195A versions prior to 2.08 have a buffer overflow vulnerability

VAR-202102-0230

Vulnerability from variot - Updated: 2023-12-18 13:32

The function CheckMic() in the Realtek RTL8195A Wi-Fi Module prior to versions released in April 2020 (up to and excluding 2.08) does not validate the size parameter for an internal function, _rt_md5_hmac_veneer() or _rt_hmac_sha1_veneer(), resulting in a stack buffer over-read which can be exploited for denial of service. An attacker can impersonate an Access Point and attack a vulnerable Wi-Fi client, by injecting a crafted packet into the WPA2 handshake. The attacker does not need to know the network's PSK. Realtek RTL8195A is an IoT microcontroller from Taiwan Realtek Semiconductor (Realtek).

Realtek RTL8195A versions prior to 2.08 have a buffer overflow vulnerability

VAR-202102-0231

Vulnerability from variot - Updated: 2023-12-18 13:27

The function DecWPA2KeyData() in the Realtek RTL8195A Wi-Fi Module prior to versions released in April 2020 (up to and excluding 2.08) does not validate the size parameter for an internal function, rt_arc4_crypt_veneer() or _AES_UnWRAP_veneer(), resulting in a stack buffer overflow which can be exploited for remote code execution or denial of service. An attacker can impersonate an Access Point and attack a vulnerable Wi-Fi client, by injecting a crafted packet into the WPA2 handshake. The attacker needs to know the network's PSK in order to exploit this. Realtek RTL8195AM is an IoT microcontroller from Taiwan Realtek Semiconductor (Realtek). Realtek RTL8195A Wi-Fi Module prior to versions 2.08 has a buffer error vulnerability

An attacker can impersonate an Access Point and attack a vulnerable Wi-Fi client, by injecting a crafted packet into the WPA2 handshake. The attacker needs to know the network\u0027s PSK in order to exploit this.

VAR-202102-0233

Vulnerability from variot - Updated: 2023-12-18 13:01

The function DecWPA2KeyData() in the Realtek RTL8195A Wi-Fi Module prior to versions released in April 2020 (up to and excluding 2.08) does not validate the size parameter for an rtl_memcpy() operation, resulting in a stack buffer overflow which can be exploited for remote code execution or denial of service. An attacker can impersonate an Access Point and attack a vulnerable Wi-Fi client, by injecting a crafted packet into the WPA2 handshake. The attacker needs to know the network's PSK in order to exploit this. Realtek RTL8195A is an IoT microcontroller from Taiwan Realtek Semiconductor (Realtek).

Realtek RTL8195A versions prior to 2.08 have a buffer overflow vulnerability

VAR-202102-0232

Vulnerability from variot - Updated: 2023-12-18 12:27

The function AES_UnWRAP() in the Realtek RTL8195A Wi-Fi Module prior to versions released in April 2020 (up to and excluding 2.08) does not validate the size parameter for a memcpy() operation, resulting in a stack buffer overflow which can be exploited for remote code execution or denial of service. An attacker can impersonate an Access Point and attack a vulnerable Wi-Fi client, by injecting a crafted packet into the WPA2 handshake. The attacker needs to know the network's PSK in order to exploit this. Realtek RTL8195AM is an IoT microcontroller from Taiwan Realtek Semiconductor (Realtek). Realtek RTL8195A Wi-Fi Module prior to versions 2.08 has a buffer error vulnerability

VAR-202106-0356

Vulnerability from variot - Updated: 2023-12-18 11:46

A stack buffer overflow in Realtek RTL8710 (and other Ameba-based devices) can lead to remote code execution via the "AES_UnWRAP" function, when an attacker in Wi-Fi range sends a crafted "Encrypted GTK" value as part of the WPA2 4-way-handshake. Realtek RTL8710 ( And other Ameba-based device ) Is vulnerable to an out-of-bounds write.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state.

Realtek RTL8710 has a buffer overflow vulnerability. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements. Realtek RTL8710 is an IoT microcontroller from Taiwan's Realtek Semiconductor Company. The following products and models are affected: Realtek RTL8710 and other ameba-based devices

VAR-202106-0357

Vulnerability from variot - Updated: 2023-12-18 10:59

A stack buffer overflow in Realtek RTL8710 (and other Ameba-based devices) can lead to remote code execution via the "memcpy" function, when an attacker in Wi-Fi range sends a crafted "Encrypted GTK" value as part of the WPA2 4-way-handshake. Realtek RTL8710 ( And other Ameba-based device ) Is vulnerable to an out-of-bounds write.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements. Realtek RTL8710 is an IoT microcontroller from Taiwan's Realtek Semiconductor Company
