Exposure of Sensitive Information to an Unauthorized Actor
CVE-2022-32742
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.
