NVD Description

Note: Versions mentioned in the description apply only to the upstream buildah package and not the buildah package as distributed by AlmaLinux. See How to fix? for AlmaLinux:9 relevant fixed versions and status.

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).
