Version 4.7.4 of tcpdump is not vulnerable to these issues according to:
https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-8767
https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-8768
https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-8769
The tcpdump commit log seems to indicate that these issues were fixes in a
different way in the following commits:
CVE-2014-8767: 4038f83ebf654804829b258dde5e0a508c1c2003
CVE-2014-8768: 9255c9b05b0a04b8d89739b3efcb9f393a617fe9
CVE-2014-8769: 9ed7ddb48fd557dc993e73f22a50dda6cedf4df7
Just drop these patches.
