An issue was discovered in Hashicorp Packer before 2.3.1. The recommended sudoers configuration for Vagrant on Linux is insecure. If the host has been configured according to this documentation, non-privileged users on the host can leverage a wildcard in the sudoers configuration to execute arbitrary commands as root.

The vagrant update process in Hashicorp vagrant-vmware-fusion 5.0.2 through 5.0.4 allows local users to steal root privileges via a crafted update request when no updates are available.

In HashiCorp Vagrant VMware Fusion plugin (aka vagrant-vmware-fusion) 5.0.1, a local attacker or malware can silently subvert the plugin update process in order to escalate to root privileges.

In HashiCorp Vagrant VMware Fusion plugin (aka vagrant-vmware-fusion) 5.0.0, a local attacker or malware can silently subvert the plugin update process in order to escalate to root privileges.

The sudo helper in the HashiCorp Vagrant VMware Fusion plugin (aka vagrant-vmware-fusion) before 4.0.21 allows local users to gain root privileges by leveraging failure to verify the path to the encoded ruby script or scrub the PATH variable.
