Vendor Workaround
The following measures reduce risk: 1. If TFTP is not required, do not enable it. Remove --enable-tftp from the dnsmasq configuration. 2. If TFTP is required, restrict it with --tftp-interface=<interface> and avoid running TFTP-only instances that serve untrusted clients on the same network. 3. Compile without TFTP support using COPTS=-DNO_TFTP if TFTP is not needed.

| Type | Values Removed | Values Added |
|---|---|---|
| Description | A flaw was found in dnsmasq. The TFTP server can serve the wrong file contents because a recently used transfer cache is not invalidated when a transfer finishes. An attacker on the local network who can request a TFTP file may cause a later client to receive previously cached data instead of the requested file. In PXE network-boot environments this can substitute attacker-chosen boot content for a victim machine. | |
