CVE-2020-11041

Improper Validation of Array Index in FreeRDP

2.2 LowFix available

In FreeRDP less than or equal to 2.0.0, an outside controlled array index is used unchecked for data used as configuration for sound backend (alsa, oss, pulse, ...). The most likely outcome is a crash of the client instance followed by no or distorted sound or a session disconnect. If a user cannot upgrade to the patched version, a workaround is to disable sound for the session. This has been patched in 2.1.0.

Updated freerdp/remmina packages fix security vulnerability

It was discovered that FreeRDP incorrectly handled certain memory operations. A remote attacker could use this issue to cause FreeRDP to crash, resulting in a denial of service, or possibly exeucte arbitrary code.

The freerdp package has been updated to version 2.1.2 to fix these issues.

Also, the remmina package has been updated to version 1.4.7 for compatibility with the updated freerdp.
