From Canon:

An international team of security researchers has drawn our attention to a vulnerability related to communications via the Picture Transfer Protocol (PTP), which is used by Canon digital cameras, as well as a vulnerability related to firmware updates.

(CVE-ID:CVE-2019-5994, CVE-2019-5995, CVE-2019-5998, CVE-2019-5999, CVE-2019-6000, CVE-2019-6001)

Due to these vulnerabilities, the potential exists for a third-party attack on the camera if the camera is connected to a PC or mobile device that has been hijacked through an unsecured network.

At this point, there have been no confirmed cases of these vulnerabilities being exploited to cause harm, but in order to ensure that our customers can use our products securely, we would like to inform you of the following workarounds for this issue.

  • Ensure the suitability of security-related settings of the devices connected to the camera, such as the PC, mobile device, and router being used.
  • Do not connect the camera to a PC or mobile device that is being used in an unsecured network, such as in a free Wi-Fi environment.
  • Do not connect the camera to a PC or mobile device that is potentially exposed to virus infections.
  • Disable the camera’s network functions when they are not being used.
  • Download the official firmware from Canon’s website when performing a camera firmware update.

There is an increase in use of PCs and mobile devices in an unsecured (free Wi-Fi) network environment where customers are not aware of the network security. As it has become prevalent to transfer images from a camera to a mobile device via a Wi-Fi connection, we will implement firmware updates for the following models that are equipped with the Wi-Fi function.


These vulnerabilities affect the following EOS-series digital SLR and mirrorless cameras:

EOS-1DX*1 *2EOS 6D Mark IIEOS 760DEOS M5
EOS-1DC*1 *2EOS 70DEOS 1300DEOS M10
EOS 5D Mark IVEOS 80DEOS 2000DEOS M100
EOS 5D Mark III*1EOS 750DEOS 4000DEOS M50
EOS 5DS*1EOS 800DEOS RPowerShot SX70 HS
EOS 5DS R*1EOS 200DEOS RPPowerShot SX740 HS
EOS 6DEOS 250DEOS M3PowerShot G5X Mark II


*1 If a WiFi adapter or a Wireless file transmitter is used, WiFi connection can be established.

*2 Ethernet connections are also affected by these vulnerabilities.

Firmware update information will be provided for each product, in turn, starting from products for which preparations have been completed.
