Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to memory information leak over SMB1. A client with write access to a share can cause server memory contents to be written into a file or printer. Some SMB1 write requests were not correctly range checked to ensure the client had sent enough data to fulfill the write, allowing server memory contents to be written into the file (or printer) instead of client supplied data. The client cannot control the area of the server memory that is written to the file (or printer).
