Description

A flaw was found in FreeRDP. This vulnerability allows a remote attacker with low privileges to disclose sensitive information from the server or proxy process memory to a downstream client. This occurs because certain functions responsible for writing Save Session Info Protocol Data Units (PDUs) use Stream_Seek instead of Stream_Zero for reserved padding fields, leading to the transmission of uninitialized heap memory that may contain cleartext credentials from previous sessions.
