  • Workaroundrsyslog-0:8.24.0-41.el7_7.ppc64le as a component of Red Hat Virtualization 4 Management Agent for RHEL 7 Hostsredhat_csaf

    This vulnerability requires the "imptcp" module to be enabled, and listening on a port that can potentially be reached by attackers. This module is not enabled by default in Red Hat Enterprise Linux 7. To check if imptcp is enabled, look for the string `$InputPTCPServerRun`in your rsyslog configuration.
