During the RDP connection sequence, the parser does not perform sufficient length validation before reading specific data fields from the network stream. A remote, unauthenticated attacker could potentially exploit this flaw by sending a specially crafted, truncated Client Control PDU. Due to missing bounds checks, the xrdp process may perform out-of-bounds memory reads, which can result in the termination of the service (Denial of Service). However, since xrdp forks a new process for each connection by default, an out-of-bounds read causing a process crash is unlikely to bring down the entire xrdp service.This issue has been fixed in version 0.10.6.1."
