CVE IDs are not assigned to UDP protocols solely on the basis of an
observed amplification-attack risk. A CVE ID can exist if the UDP
reply traffic simply cannot ever have any legitimate purpose for users
of a protocol. The general case of the interaction between UDP
amplification and CVE was discussed between MITRE and CERT in 2013;
this may be the reason that no CVE ID is listed in the
https://www.kb.cert.org/vuls/id/419128 document.
We can, however, assign a CVE ID to a vendor's announcement of a
required security update, such as on the https://libreswan.org/ home
page:
"libreswan 3.16 vulnerable to DDOS attack. Please upgrade to 3.17"
Use CVE-2016-5361 for this issue only in the libreswan codebase.
> https://bugzilla.redhat.com/show_bug.cgi?id=1308508#c6
> This is tracked via upstream bug:
> https://bugs.libreswan.org/show_bug.cgi?id=262
We don't think that Bug 262 tracks this "one update to libreswan IKEv1
to reduce amplification caused by retransmits" issue. Bug 262 is about
a possible functionality problem in the 3.17 release, It is marked
"Importance: Low enhancement."
