Vulnerability Name:

CVE-2022-32742 (CCN-232306)

Assigned:2022-07-27
Published:2022-07-27
Updated:2022-08-31
Summary:A flaw was found in Samba. 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 written to the file (or printer).
