This release of Mbed TLS provides bug fixes and minor enhancements. This
release includes fixes for following security issues:
* Timing side channel in private key RSA operations (CVE-2024-23170)
Mbed TLS is vulnerable to a timing side channel in private key RSA
operations. This side channel could be sufficient for an attacker to
recover the plaintext. A local attacker or a remote attacker who is
close to the victim on the network might have precise enough timing
measurements to exploit this. It requires the attacker to send a large
number of messages for decryption.
* Buffer overflow in mbedtls_x509_set_extension() (CVE-2024-23775)
When writing x509 extensions we failed to validate inputs passed in to
mbedtls_x509_set_extension(), which could result in an integer overflow,
causing a zero-length buffer to be allocated to hold the extension. The
extension would then be copied into the buffer, causing a heap buffer
overflow.
Fixes: CVE-2024-23170, CVE-2024-23775
