Summary
The Trivial File Transfer Protocol (TFTP) is typically used only for booting diskless workstations. The tftp packages include the tftp and tftp-server subpackages. The tftp subpackage provides the user interface for TFTP and the tftp-server subpackage provides the server. This allows users to transfer files to and from a remote machine.
Security Fix(es):
* tftp: tftp-hpa: Denial of Service due to out-of-bounds read/write in remap engine (CVE-2026-85234)
