(CVE-2017-17426)USN-3239-2ubuntueglibc+1eglibc, glibc regression
USN-3239-1 fixed vulnerabilities in the GNU C Library. Unfortunately,
the fix for CVE-2015-5180 introduced an internal ABI change within
the resolver library. This update reverts the change. We apologize
for the inconvenience.
Please note that long-running services that were restarted to compensate
for the USN-3239-1 update may need to be restarted again.
