Improper Validation of Consistency within Input vulnerability in Erlang OTP ssl (tls handshake 1 3, ssl handshake and tls client ticket store modules) allows a malicious TLS 1.3 server to cause a denial of service of the ssl application on the client node.

The TLS 1.3 client decodes the extensions of a NewSessionTicket message as if they came from EncryptedExtensions. It therefore accepts a 0-length early data extension, a form that is only valid in ClientHello and EncryptedExtensions. With {session tickets, auto}, the client stores the ticket in the node-global tls client ticket store. On the next automatic resumption, tls handshake 1 3:get max early data/1 crashes the store with a case clause. Repeated crashes can exceed the restart intensity of the ssl supervisors, which use the rest for one strategy, and take down ssl for all connections on the node.

This issue affects OTP from OTP 23.3 before OTP 27.3.4.19, OTP 28.5.0.8, and OTP 29.1.2, corresponding to ssl from 10.3 before 11.2.12.14, 11.6.0.7, and 11.7.8.
