Descriptions

In wolfSSL before 5.5.2, if callback functions are enabled (via the WOLFSSL_CALLBACKS flag), then a malicious TLS 1.3 client or network attacker can trigger a buffer over-read on the heap of 5 bytes. (WOLFSSL_CALLBACKS is only intended for debugging.)

En wolfSSL anterior a 5.5.2, si las funciones callback están habilitadas (a través del indicador WOLFSSL_CALLBACKS), entonces un cliente TLS 1.3 malicioso o un atacante de red puede desencadenar una sobrelectura del búfer de memoria de 5 bytes. (WOLFSSL_CALLBACKS solo está destinado a la depuración).

wolfSSL versions prior to 5.5.2 suffer from a heap buffer over-read with WOLFSSL_CALLBACKS and can be triggered with a single Client Hello message.
