Yes, my apologies, the upstream libc fixes for CVE-2014-9761 did some reworking of functions to eliminate some repeated vulnerable code, using internal functions to do the work instead. Unfortunately, this did introduce new function references between libc and libm, causing the problems seen above. Unfortunately, these changes were applied to libc in Ubuntu 14.04 LTS and Ubuntu 15.10 as well, so I'm surprised the same problem was not seen there, too. There was no update for Ubuntu 16.04 LTS, so no issues should be seen there.

Joi: yes, the reboot motd notification was triggered with this update (and will be for future libc updates). That doesn't help you if you can't log in to see it. :(
