tcpdump vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

• Ubuntu 14.10
• Ubuntu 14.04 LTS
• Ubuntu 12.04 LTS

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 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.

The problem can be corrected by updating your system to the following package version:

Ubuntu 14.10:

tcpdump 4.6.2-1ubuntu1.2

Ubuntu 14.04 LTS:

tcpdump 4.5.1-2ubuntu1.2

Ubuntu 12.04 LTS:

tcpdump 4.2.1-1ubuntu2.2
