Subject: 
tcpdump-4.9.3-1.el8
Affected Channels: 
Asianux Server 8 for x86_64
Severity: 
Moderate
Description: 

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).

Security Fix(es):

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