Confined use of Log4j version 1.x 

The following products in Secure e-communications Suite (former Deltagon products) have Log4j version 1.x package dependancy if they have been installed on Red Hat Enterprise Linux 7 or Red Hat Enterprise Linux 6: 

  • collabRoom (Secure e-communications Suite)
  • secSigned (Secure e-communications Suite)
  • Sec@GW (Secure e-communications Suite), used only in rare, non-default configuration.

While Tectia ConnectSecure JAVA SDK itself does not use Log4j, any customers who have implemented a JAVA application with Tectia ConnectSecure JAVA SDK are advised to verify their own implementation and 3rd party dependencies.

SSH Communication Security also recommends every customer to upgrade their operating systems with the latest security fixes.

Log4j version 2.x users are advised to update to the latest Log4j version (2.17.0).
