  "details": "xrdp is an open source RDP server. Versions 0.10.6 and prior contain a timing side-channel vulnerability in the login interface. Due to a discrepancy in response processing times, a remote attacker can infer the existence of a username on the system, leading to unauthorized information disclosure via username enumeration. This issue has been fixed in version 0.10.6.1.",
