libczmq4.armv7hl: I: binary-or-shlib-calls-gethostbyname /usr/lib/libczmq.so.4.2.1
The binary calls gethostbyname(). Please port the code to use getaddrinfo().

libczmq4.armv7hl: W: missing-call-to-setgroups-before-setuid /usr/lib/libczmq.so.4.2.1
This executable is calling setuid and setgid without setgroups or initgroups.
There is a high probability this means it didn't relinquish all groups, and
this would be a potential security issue to be fixed. Seek POS36-C on the web
for details about the problem.
