Man-in-the-middle attackers or a malicious server can crash TLS 1.2 clients during a handshake. If an attacker injects a large ticket (more than 256 bytes) into a NewSessionTicket message in a TLS 1.2 handshake, and the client has a non-empty session cache, the session cache frees a pointer that points to unallocated memory, causing the client to crash with a \"free(): invalid pointer\" message. NOTE: It is likely that this is also exploitable during TLS 1.3 handshakes between a client and a malicious server. With TLS 1.3, it is not possible to exploit this as a man-in-the-middle."}, {"lang": "es", "value": "Se ha detectado un problema en wolfSSL versiones anteriores a 5.5.0 (cuando es usado --enable-session-ticket); sin embargo, s\u00f3lo la versi\u00f3n 5.3.0 es explotable.
