Several vulnerabilities have been discovered in tcpdump, a command-line
network traffic analyzer. These vulnerabilities might result in denial of
service or, potentially, execution of arbitrary code.

For the oldstable distribution (stretch), these problems have been fixed
in version 4.9.3-1~deb9u1.

For the stable distribution (buster), these problems have been fixed in
