ESF-IDF is the Espressif Internet of Things (IOT) Development Framework. In versions 5.2.6, 5.3.5, 5.4.4, 5.5.4, and 6.0, a heap buffer overflow exists in the Security Scheme 2 (SRP6a) session-setup path of the protocomm component. The first-phase handler (handle_session_command0...
ESF-IDF is the Espressif Internet of Things (IOT) Development Framework. In versions 5.5.4 and 6.0, several ESP-TEE secure-service wrappers in esp_secure_services.c and esp_secure_services_iram.c validated only some of the caller-supplied pointer arguments, leaving input pointer...
ESF-IDF is the Espressif Internet of Things (IOT) Development Framework. In versions 5.5.4 and 6.0, the esp_tee component exposes secure-service wrappers in esp_secure_services.c and esp_secure_services_iram.c that bridge calls from the user application (i.e. the REE) to TEE-prot...
ESF-IDF is the Espressif Internet of Things (IOT) Development Framework. In versions 5.2.7, 5.3.5, 5.4.4, 5.5.4, and 6.0.1, an out-of-bounds read flaw exists in the DHCP server option parser (parse_options() in components/lwip/apps/dhcpserver/dhcpserver.c) shipped with ESP-IDF's...
ESF-IDF is the Espressif Internet of Things (IOT) Development Framework. In versions 5.2.6, 5.3.5, 5.4.4, 5.5.4, and 6.0, a NULL-pointer dereference exists in the WebSocket subprotocol-negotiation path of the esp_http_server component. While parsing the client-supplied Sec-WebSoc...
Espressif Shared GitHub DangerJS is a reusable GitHub Action CI DangerJS workflow for Espressif GitHub projects. Prior to 1.0.1, the action's entrypoint.sh invoked DangerJS from the caller's workspace after copying the fork's checkout into it, creating an untrusted search path fo...
arduino-esp32 is an Arduino core for the ESP32, ESP32-S2, ESP32-S3, ESP32-C3, ESP32-C6 and ESP32-H2 microcontrollers. Prior to 3.3.8, the WebServer multipart form parser in arduino-esp32 allocates a Variable Length Array (VLA) on the stack whose size is derived from an attacker-c...
arduino-esp32 is an Arduino core for the ESP32, ESP32-S2, ESP32-S3, ESP32-C3, ESP32-C6 and ESP32-H2 microcontrollers. Prior to 3.3.8, the WebServer Digest authentication implementation in arduino-esp32 computes the authentication hash using the URI field from the client's Authori...
arduino-esp32 is an Arduino core for the ESP32, ESP32-S2, ESP32-S3, ESP32-C3, ESP32-C6 and ESP32-H2 microcontrollers. Prior to 3.3.8, there is a remotely reachable memory corruption issue in the NBNS packet handling path. When NetBIOS is enabled by calling NBNS.begin(...), the de...
ESF-IDF is the Espressif Internet of Things (IOT) Development Framework. In versions 5.5.2, 5.4.3, 5.3.4, 5.2.6, and 5.1.6, an out-of-bounds read vulnerability was reported in the BLE ATT Prepare Write handling of the BLE provisioning transport (protocomm_ble). The issue can be t...
ESF-IDF is the Espressif Internet of Things (IOT) Development Framework. In versions 5.5.2, 5.4.3, 5.3.4, 5.2.6, and 5.1.6, a use-after-free vulnerability was reported in the BLE provisioning transport (protocomm_ble) layer. The issue can be triggered by a remote BLE client while...

Espressif ESP-IDF USB Host HID (Human Interface Device) Driver allows access to HID devices. Prior to 1.1.0, calls to hid_host_device_close() can free the same usb_transfer_t twice. The USB event callback and user code share the hid_iface_t state without locking, so both can tear...
Espressif ESP-IDF USB Host HID (Human Interface Device) Driver allows access to HID devices. Prior to 1.1.0, usb_class_request_get_descriptor() frees and reallocates hid_device->ctrl_xfer when an oversized descriptor is requested but continues to use the stale local pointer, lead...
Espressif ESP-IDF USB Host UVC Class Driver allows video streaming from USB cameras. Prior to 2.4.0, a vulnerability in the esp-usb UVC host implementation allows a malicious USB Video Class (UVC) device to trigger a stack buffer overflow during configuration-descriptor parsing....
ESF-IDF is the Espressif Internet of Things (IOT) Development Framework. In versions 5.5.1, 5.4.3, 5.3.4, 5.2.6, 5.1.6, and earlier, in the avrc_vendor_msg() function of the ESP-IDF BlueDroid AVRCP stack, the allocated buffer size was validated using AVRC_MIN_CMD_LEN (20 bytes)....
