Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1702 advisory.

The following packages have been upgraded to a later upstream version: rsyslog (8.1911.0). (BZ#1740683)

Security Fix(es):

* rsyslog: heap-based overflow in contrib/pmaixforwardedfrom/pmaixforwardedfrom.c (CVE-2019-17041)
