versions in debian, probably devuan needs to address this too.

seems a new version (0.105-31.1+devuan1) just came in ceres, which 
merges debian/0.105-31.1, so this is probably fixed for daedalus/ceres!

leaving it open, so you can confirm security fix & close as you think.

thanks!

Updated binaries are already in unstable, daedalus, chimaera-security and
