Description
Simon Butcher reports: When the truncated HMAC extension is enabled and CBC is used, sending a malicious application packet can be used to selectively corrupt 6 bytes on the peer's heap, potentially leading to a crash or remote code execution. This can be triggered remotely from either side in both TLS and DTLS. When RSASSA-PSS signature verification is enabled, sending a maliciously constructed certificate chain can be used to cause a buffer overflow on the peer's stack, potentially leading to crash or remote code execution. This can be triggered remotely from either side in both TLS and DTLS.
