Updated hamlib packages fix a security vulnerability
Publication date: 09 Oct 2026Modification date: 09 Oct 2026
Type: security
Affected Mageia releases : 10
CVE: CVE-2026-54634
Description
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.
