Overview
Affected versions of this package are vulnerable to Out-of-bounds Read via the check_server_certificate function. An attacker can cause the application to read memory outside of valid buffer boundaries by sending a specially crafted Certificate handshake message with a manipulated fragment_length value, exploiting missing buffer length validation before certain memory operations during DTLS epoch 0 on both client and server paths. This can result in denial of service, particularly on memory-constrained devices.
