Detailsinfo

A vulnerability was found in Google Go up to 1.7.5/1.8.1 on AMD64 (Programming Language Software). It has been declared as problematic. This vulnerability affects an unknown code of the component ScalarMult. The manipulation with an unknown input leads to a cryptographic issue vulnerability (Key). The CWE definition for the vulnerability is CWE-310. As an impact it is known to affect confidentiality. CVE summarizes:

A bug in the standard library ScalarMult implementation of curve P-256 for amd64 architectures in Go before 1.7.6 and 1.8.x before 1.8.2 causes incorrect results to be generated for specific input points. An adaptive attack can be mounted to progressively extract the scalar input to ScalarMult by submitting crafted points and observing failures to the derive correct output. This leads to a full key recovery attack against static ECDH, as used in popular JWT libraries.
