AI-suggested
Apply the update to mbedtls version 2.28.10 or later where these issues are fixed. TLS clients should ensure mbedtls_ssl_set_hostname() is called when using certificate authentication to avoid handshake failures and insecure server authentication. The update includes official fixes for the described vulnerabilities and bugs.
Description
This security update for mbedtls-2 addresses multiple issues including enabling SRTP and DTLS protocols, changing default TLS client behavior to require hostname verification, fixing a TLS 1.2 handshake vulnerability related to memory allocation or cryptographic hardware failures, and several bug fixes. The update enforces that TLS clients call mbedtls_ssl_set_hostname() to prevent server impersonation, returning an error if not set. It also zeroizes temporary heap buffers used in PSA operations and fixes potential double close file descriptor problems and compilation issues.
