Descriptions

The ScalarMult and ScalarBaseMult methods of the P256 Curve may return an incorrect result if called with some specific unreduced scalars (a scalar larger than the order of the curve). This does not impact usages of crypto/ecdsa or crypto/ecdh.

A flaw was found in the crypto/internal/nistec golang library. The ScalarMult and ScalarBaseMult methods of the P256 Curve may return an incorrect result if called with some specific unreduced scalars, such as a scalar larger than the order of the curve. This does not impact usages of crypto/ecdsa or crypto/ecdh.

OpenShift API for Data Protection enables you to back up and restore application resources, persistent volume data, and internal container images to external backup storage. OADP enables both file system-based and snapshot-based backups for persistent volumes. Issues addressed include a denial of service vulnerability.
