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 2.0.0-rc4

Description: The issue is related to Out-Of-Bounds Reads in the NTLM Authentication module, which can result in a Denial of Service. This is caused by a buffer overflow read in the memory. An attacker could exploit this to cause a service disruption.

Recommendations: For versions prior to 2.0.0-rc4, update to version 2.0.0-rc4 or later to resolve the issue. As a temporary workaround, consider restricting access to the NTLM Authentication module until a patch is applied.
