arbitrary code or Denial of Service.
Background
==========
tcpdump is a tool for capturing and inspecting network traffic.
Affected packages

Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-analyzer/tcpdump < 4.6.2-r1 >= 4.6.2-r1
Description
