From fec2888ae568ef392529bb1c6f75178cc8aad8c7 Mon Sep 17 00:00:00 2001 From: Magnus Kroken Date: Sat, 25 Jul 2020 14:19:28 +0200 Subject: mbedtls: update to 2.16.7 Mbed TLS 2.16.7 is a maintenance release of the Mbed TLS 2.16 branch, and provides bug fixes and minor enhancements. This release includes fixes for security issues and the most severe one is described in more detail in a security advisory: https://tls.mbed.org/tech-updates/security-advisories/mbedtls-security-advisory-2020-07 * Fix a side channel vulnerability in modular exponentiation that could reveal an RSA private key used in a secure enclave. * Fix side channel in mbedtls_ecp_check_pub_priv() and mbedtls_pk_parse_key() / mbedtls_pk_parse_keyfile() (when loading a private key that didn't include the uncompressed public key), as well as mbedtls_ecp_mul() / mbedtls_ecp_mul_restartable() when called with a NULL f_rng argument. An attacker with access to precise enough timing and memory access information (typically an untrusted operating system attacking a secure enclave) could fully recover the ECC private key. * Fix issue in Lucky 13 counter-measure that could make it ineffective when hardware accelerators were used (using one of the MBEDTLS_SHAxxx_ALT macros). Due to Mbed TLS moving from ARMmbed to the Trusted Firmware project, some changes to the download URLs are required. For the time being, the ARMmbed/mbedtls Github repository is the canonical source for Mbed TLS.
