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. golang: crypto/elliptic: panic caused by oversized scalar A moderate severity flaw was found in Go’s crypto/elliptic package in the generic P-256 implementation. If a scalar input longer than 32 bytes is supplied, P256().ScalarMult or P256().ScalarBaseMult can panic, causing the application to crash. Indirect uses via crypto/ecdsa and crypto/tls are not affected. This issue impacts availability but does not affect confidentiality or integrity. Only certain platforms (non-amd64, non-arm64, non-ppc64le, non-s390x) may be affected. Red Hat Enterprise Linux 7, 8 and 9 are affected, because the code-base is affected by this vulnerability. Red Hat Product Security has rated this issue as having Moderate security impact, and the issue is not currently planned to be addressed in future updates for Red Hat Enterprise Linux 7, hence, marked as Out-of-Support-Scope. Red Hat Developer Tools - Compilers (go-toolset-1.16-golang & go-toolset-1.17-golang), ships the vulnerable code and affected by this vulnerability.
