Description
FreeRDP from 2.0.0 before 3.32.0 contains an insecure permission vulnerability in winpr-makecert that creates unencrypted private keys without owner-only file modes. Local users on multi-user Unix hosts can read world-readable key files or open PFX files protected by the hard-coded default password to steal private keys.
