    Title
    arduino-TuyaOpen WiFiUDP Null Pointer Dereference Denial of Service
    Summary
    arduino-TuyaOpen before version 1.2.1 contains a null pointer dereference vulnerability in the WiFiUDP component. An attacker on the same local area network can send a large volume of malicious UDP packets that trigger a null pointer dereference, resulting in a denial-of-service condition.

    Title
    arduino-TuyaOpen DnsServer Heap-Based Buffer Overflow Remote Code Execution
    Summary
    arduino-TuyaOpen before version 1.2.1 contains a heap-based buffer overflow vulnerability in the DnsServer component. An attacker on the same local area network who controls the LAN DNS server can send malicious DNS responses to overflow the heap buffer, potentially allowing execution of arbitrary code on affected embedded devices.

    Title
    arduino-TuyaOpen DnsServer Heap-Based Buffer Overflow Remote Code Execution
    Summary
    arduino-TuyaOpen before version 1.2.1 contains a heap-based buffer overflow vulnerability in the DnsServer component. An attacker on the same local area network who controls the LAN DNS server can send malicious DNS responses to overflow the heap buffer, potentially allowing execution of arbitrary code on affected embedded devices.

    Title
    arduino-TuyaOpen WiFiMulti Single-Byte Buffer Overflow Remote Code Execution
    Summary
    arduino-TuyaOpen before version 1.2.1 contains a single-byte buffer overflow vulnerability in the WiFiMulti component. When the victim's smart hardware connects to an attacker-controlled AP hotspot, the attacker can exploit the overflow to execute arbitrary code on the affected embedded device.
