Ubuntu 18.04: USN-4082-1 Important: tcpdump Security Update

ubuntu
Calendar Grey February 21, 2017
Dist Ubuntu Esm H88
The Ubuntu Security Announcement USN-3752-1 addresses vulnerabilities in OpenSSH that may permit privilege escalation or Denial of Service attacks.
tcpdump could be made to crash or run programs if it received specially crafted network traffic.

Summary

tcpdump could be made to crash or run programs if it received specially

crafted network traffic.

Software Description:

- tcpdump: command-line network traffic analyzer

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.
