Prior to 4.7.2, the unauthenticated rigctld send raw command on TCP port 4532 reaches rigctl send raw() in tests/rigctl parse.c, which writes a NUL byte at buf[buf len + 1] outside its 200-byte stack buffer, and rig send raw() in src/rig.c, which copies reply len - 1 bytes instead of the actual nbytes received. A remote client can send the CR terminator with a short payload to trigger both flaws in one command under the default no-password configuration. The out-of-bounds write can crash the daemon or corrupt adjacent stack memory, while the oversized copy can return up to 198 bytes of uninitialized stack data to the client. This issue is fixed in version 4.7.2.
