Overview
Affected versions of this package are vulnerable to Out-of-bounds Write in the processing of specially crafted RDP messages due to an integer overflow that leads to the allocation of an undersized memory buffer. An attacker can execute arbitrary code or cause a denial of service by sending malicious RDP messages that trigger writes beyond the boundaries of the allocated buffer.
