USN-2580-1: tcpdump vulnerabilities

Publication date

27 April 2015

Overview

tcpdump could be made to crash or run programs if it received specially crafted network traffic.


Packages

  • tcpdump - command-line network traffic analyzer

Details

It was discovered that tcpdump incorrectly handled printing 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.
