Description
A flaw was found in FreeRDP. When software-based smartcard authentication is used on multi-user systems, FreeRDP writes a temporary copy of the private key to a shared directory without enforcing owner-only file permissions. A local, unprivileged attacker can access this shared directory and read the world-readable file, leading to the disclosure of sensitive cryptographic credentials.
