NVD Description

Note: Versions mentioned in the description apply only to the upstream glibc package and not the glibc package as distributed by Ubuntu. See How to fix? for Ubuntu:16.04 relevant fixed versions and status.

The DNS stub resolver in the GNU C Library (aka glibc or libc6) before version 2.26, when EDNS support is enabled, will solicit large UDP responses from name servers, potentially simplifying off-path DNS spoofing attacks due to IP fragmentation.
