PenguinTrace - Tool To Show How Code Runs At The Hardware Level

penguinTrace is intended to help build an understanding of how programs run at the hardware level. It provides a way to see what instructions compile to, and then step through those instructions and see how they affect machine state as well as how this maps back to variables in the original...

GO-2022-0187 Incorrect computation for P-256 curves in crypto/elliptic

The ScalarMult implementation of curve P-256 for amd64 architectures generates incorrect results for certain specific input points. An adaptive attack can progressively extract the scalar input to ScalarMult by submitting crafted points and observing failures to derive correct output. This leads ...

GO-2022-0435 Panic due to large inputs affecting P-256 curves in crypto/elliptic

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...
