Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2020:4760 advisory.

The tcpdump packages contain the tcpdump utility for monitoring network traffic. The tcpdump utility can capture and display the packet headers on a particular network interface or on all interfaces.

The following packages have been upgraded to a later upstream version: tcpdump (4.9.3). (BZ#1804063)
