Summary

IBM Watson Discovery for IBM Cloud Pak for Data contains a vulnerable version of Go.

Vulnerability Details

CVEID:CVE-2020-28362
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by improper input validation by the math/big.Int methods. By sending a specially-crafted inputs, a remote attacker could exploit this vulnerability to cause the application to crash.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/191976 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2020-28367
**DESCRIPTION:**Golang Go could allow a remote attacker to execute arbitrary code on the system, caused by a argument injection flaw in go command when cgo is in use in build time. By using a specially-crafted package, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/191979 for the current score.
