Descriptions

The generic P-256 feature in crypto/elliptic in Go before 1.17.9 and 1.18.x before 1.18.1 allows a panic via long scalar input.

La característica genérica P-256 en crypto/elliptic en Go versiones anteriores a 1.17.9 y versiones 1.18.x anteriores a 1.18.1, permite un pánico por medio de una entrada escalar larga

An integer overflow flaw was found in Golang's crypto/elliptic library. This flaw allows an attacker to use a crafted scaler input longer than 32 bytes, causing P256().ScalarMult or P256().ScalarBaseMult to panic, leading to a loss of availability.
