The vulnerability exists due to integer overflow in the Golang's library crypto/elliptic. A remote attacker can send a specially crafted scalar input longer than 32 bytes to cause P256().ScalarMult or P256().ScalarBaseMult to panic and perform a denial of service attack.
2) Buffer overflow (CVE-ID: CVE-2022-24675)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists in the Golang's library encoding/pem. A remote attacker can send to victim a large (more than 5 MB) PEM input to cause a stack overflow in Decode and perform a denial of service (DoS) attack.
3) Improper Certificate Validation (CVE-ID: CVE-2022-27536)
The vulnerability allows a remote attacker to perform a denial of service attack.
