CVE-2014-7250
The TCP stack in 4.3BSD Net/2, as used in FreeBSD 5.4, NetBSD possibly 2.0, and OpenBSD possibly 3.6, does not properly implement the session timer, which allows remote attackers to cause a denial of service (resource consumption) via crafted packets.

Does this matter?
Lower severity and a low EPSS score (4.75%). Track it; it rarely justifies an emergency change on its own.
