The mbedtls package has been updated to fix several security issues. Fixed a heap corruption issue in the implementation of the truncated HMAC extension. When the truncated HMAC extension is enabled and CBC is used, sending a malicious application packet could be used to selectively corrupt 6 bytes on the peer’s heap, which could potentially lead to crash or remote code execution. The issue could be triggered remotely from either side in both TLS and DTLS. (CVE-2018-0488) Fixed a buffer overflow in RSA-PSS verification when the hash was too large for the key size, which could potentially lead to crash or remote code execution. (CVE-2018-0487)
