Description
FreeRDP from 3.0.0 before 3.32.0 contains an incorrect permission assignment vulnerability that allows local users to read private keys written by crypto_write_pem without owner-only permissions. Attackers on multi-user Unix hosts can enumerate the shared temporary directory during soft-smartcard logon to read the world-readable PKINIT private-key copy.
