Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.

Description

aws/resource_aws_iam_user_login_profile.go in the HashiCorp Terraform Amazon Web Services (AWS) provider through v1.12.0 has an inappropriate PRNG algorithm and seeding, which makes it easier for remote attackers to obtain access by leveraging an IAM account that was provisioned with a weak password.
