Through fuzzing of network capture .pcap files, we have identified 16 crashes with unique stack traces in tcpdump. These crashes are caused by heap-based out-of-bounds memory reads, and can be reproduced with the latest tcpdump source code from GitHub, compiled with AddressSanitizer:

--- cut ---
$ ./tcpdump --version
tcpdump version 4.10.0-PRE-GIT
libpcap version 1.10.0-PRE-GIT (with TPACKET_V3)
OpenSSL 1.1.0h  27 Mar 2018
Compiled with AddressSanitizer/CLang.
--- cut ---

The command line options we used are as follows:

--- cut ---
$ ./tcpdump -e -XX -vvv -R $file
--- cut ---

A summary of each crash with the two top-level callstack items are shown below:
