Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4252-1 advisory.

    Multiple security issues were discovered in tcpdump. A remote attacker could use these issues to cause     tcpdump to crash, resulting in a denial of service, or possibly execute arbitrary code.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Tcpdump is vulnerable to a buffer overflow, caused by improper bounds checking by the lmp_print_data_link_subobjs function in print-lmp.c.
By sending specially-crafted data, a remote attacker could overflow a buffer and cause the application to crash.
