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)

Security Fix(es):

* tcpdump: SMB data printing mishandled (CVE-2018-10103)
