High

Base vector

AV:N/AC:L/Au:N/C:N/I:N/A:C

Name of the Vulnerable Software and Affected Versions FreeRDP versions prior to 2.9.0

Description The issue is related to insufficient input validation in the urbdrc channel of the FreeRDP remote desktop protocol implementation, which can lead to a division by zero error. This can be exploited by a remote attacker to cause a denial of service by crashing the client. A malicious server can trick a FreeRDP-based client into crashing with a division by zero error.

Recommendations For versions prior to 2.9.0, upgrade to version 2.9.0 to address the issue. If an upgrade is not possible, do not use the /usb redirection switch as a temporary workaround to minimize the risk of exploitation.
