CVE-2022-41724

Panic on large handshake records in crypto/tls

Published Feb 28, 2023 CVSS 3.1 · 7.5 High EPSS 1.1% KEV · Not listed
Description
Large handshake records may cause panics in crypto/tls. Both clients and servers may send large TLS handshake records which cause servers and clients, respectively, to panic when attempting to construct responses. This affects all TLS 1.3 clients, TLS 1.2 clients which explicitly enable session resumption (by setting Config.ClientSessionCache to a non-nil value), and TLS 1.3 servers which request client certificates (by setting Config.ClientAuth >= RequestClientCert).
