The OpenSSL RSA Key generation algorithm has been shown to be vulnerable to a cache timing side channel attack. An attacker with sufficient access to mount cache timing attacks during the RSA key generation process could recover the private key. Fixed in OpenSSL 1.1.0i-dev (Affected 1.1.0-1.1.0h). Fixed in OpenSSL 1.0.2p-dev (Affected 1.0.2b-1.0.2o).

Fixedphoenix_contact_psirt
Update to Firmware Release 2019.0 LTS or later. Update to PLCnext Engineer Release 2019.0 LTS or later. Update A, 30.08.2019 With Firmware Release 2019.6 an option was added to the web-based management that allows the user to permanently disable storage of configuration data to the SD-Card. The device can now be operated without SD-Card and ignores any inserted SD-Card. We recommend using this new configuration option for application scenarios where physical access to the device cannot be restricted effectively.
