Description
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the mbedtls_ecdsa_der_to_raw() and
mbedtls_ecdsa_raw_to_der() functions when the bits parameter is larger than the
largest supported curve and PSA is disabled. A remote attacker can send specially crafted packets to the application, trigger a stack-based buffer overflow and perform a denial of service (DoS) attack.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
