CVE-2022-24883: Fedoraproject Fedora

Critical severity, CVSS 9.8. EPSS: 2.3% chance of exploitation in the next 30 days.

FreeRDP is a free implementation of the Remote Desktop Protocol (RDP). Prior to version 2.7.0, server side authentication against a `SAM` file might be successful for invalid credentials if the server has configured an invalid `SAM` file path. FreeRDP based clients are not affected. RDP server implementations using FreeRDP to authenticate against a `SAM` file are affected. Version 2.7.0 contains a fix for this issue. As a workaround, use custom authentication via `HashCallback` and/or ensure the `SAM` database path configured is valid and the application has file handles left.

Affected products

• Fedoraproject Fedora: version 34 only; version 35 only; version 36 only
• Freerdp Freerdp: before 2.7.0 (fixed in 2.7.0)
