CVE-2022-23806: Critical severity IBM Cloud Pak for Security vulnerability
A flaw was found in the elliptic package of the crypto library in golang when the IsOnCurve function could return true for invalid field elements. This flaw allows an attacker to take advantage of this undefined behavior, affecting the availability and integrity of the resource.
Other sources
Curve.IsOnCurve in crypto/elliptic in Go before 1.16.14 and 1.17.x before 1.17.7 can incorrectly return true in situations with a big.Int value that is not a valid field element.
Golang Go is vulnerable to a denial of service, caused by a flaw with IsOnCurve function returns true for invalid field elements. By sending a specially-crafted request, an attacker could exploit this vulnerability to causes a panic in ScalarMult, and results in a denial of condition.
