Name of the Vulnerable Software and Affected Versions FreeRDP versions 2.0.0-beta1+android11

Description A denial of service issue exists due to the improper handling of proprietary server certificates. An attacker can send a specially crafted challenge packet, causing the program to terminate and resulting in a denial of service condition. This can be triggered by compromising the server or using a man-in-the-middle attack.

Recommendations For FreeRDP version 2.0.0-beta1+android11, consider restricting access to the certificate reading functionality until a patch is available. As a temporary workaround, implement additional validation on challenge packets to prevent specially crafted packets from causing program termination.
