Workaround
+
The most severe vulnerability, CVE-2017-7478, which allows a remote
+
unauthenticated attacker to cause a denial of service, can be mitigated
+
by setting up tls-auth or tls-crypt. Note that this requires changing
+
both server and clients configurations.
Impact
+
A remote, unauthenticated attacker can crash a server not using tls- auth or tls-crypt by sending a packet with an unexpected payload size.
+
A remote, authenticated attacker can crash a server using an AEAD mode cipher by sending crafted data to exhaust the packet counter.
