| summary: Panic due to large inputs affecting P-256 curves in crypto/elliptic |
| description: |- |
| A crafted scalar input longer than 32 bytes can cause P256().ScalarMult or |
| P256().ScalarBaseMult to panic. Indirect uses through crypto/ecdsa and |
| crypto/tls are unaffected. amd64, arm64, ppc64le, and s390x are unaffected. |
