CVE-2015-6496 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:18.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream conntrack-tools package and not the conntrack-tools package as distributed by Ubuntu.
conntrackd in conntrack-tools 1.4.2 and earlier does not ensure that the optional kernel modules are loaded before using them, which allows remote attackers to cause a denial of service (crash) via a (1) DCCP, (2) SCTP, or (3) ICMPv6 packet.
