Details

It was discovered that tcpdump incorrectly handled certain packets. A
remote attacker could use this issue to cause tcpdump to crash, resulting
in a denial of service, or possibly execute arbitrary code.

In the default installation, attackers would be isolated by the tcpdump
AppArmor profile.
