From 403039c562e16f4242e3485d8f076ea726dd8744 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Mon, 24 Aug 2020 12:11:29 +0200 Subject: [PATCH] wolfssl: Update to version 4.5.0 This fixes the following security problems: * In earlier versions of wolfSSL there exists a potential man in the middle attack on TLS 1.3 clients. * Denial of service attack on TLS 1.3 servers from repetitively sending ChangeCipherSpecs messages. (CVE-2020-12457) * Potential cache timing attacks on public key operations in builds that are not using SP (single precision). (CVE-2020-15309) * When using SGX with EC scalar multiplication the possibility of side- channel attacks are present. * Leak of private key in the case that PEM format private keys are bundled in with PEM certificates into a single file. * During the handshake, clear application_data messages in epoch 0 are processed and returned to the application.
