This Firmware do fix the issue CVE-2017-9628 related to Ethernet frame padding information leakage. PCD Firmware 1.28.16 or 1.24.69 fix the Ethernet frame padding information leakage (FAQ #102011).
Programmable PCD devices that act as S-BUS master on RS485 with PCD Firmware >= 1.28.20 and = 1.28.34. The firmware update of the PCD who act as S-Bus master with a firmware 1.28.34 or newer solves the issue. This could lead to the situation that for example the PCD S-Bus master don’t receive actual values from E-Line RIO’s or that the program download of a PCD program from the PC to a Slave PCD which is located behind a gateway PCD, fails. It’s possible that the some of the S-Bus telegrams transferred from the PCD S-Bus master to the S-Bus slaves over RS485 are malformed, and the S-Bus slave does reject the request from the master.
