USN-3205-1: tcpdump vulnerabilities

Severity

Medium

Vendor

Canonical Ubuntu

Versions Affected

  • Canonical Ubuntu 14.04 LTS

Description

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.

      • 3151.x versions prior to 3151.11
