| Doc Text: |
A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol (RDP). A remote attacker could exploit this vulnerability by sending a specially crafted RDP message. This can lead to an undefined behavior where a wrapped value is used as a shift exponent, causing an approximately 80 billion iteration loop. This results in a Denial of Service (DoS) due to excessive CPU utilization.
