CVE-2020-36476

Summary

An issue in Mbed TLS prior to version 2.24.0, as well as pre-release 2.16.8 LTS and 2.7.17 LTS, exposes an application data security risk. The vulnerability arises from insufficient zeroization of plaintext buffers in the mbedtls_ssl_read function, leading to potential information leakage of sensitive data remnants from memory. This flaw emphasizes the importance of proper memory management to ensure data confidentiality.
