Fixed In Version: glibc-2.17-106.el7_2.6
Doc Type: Bug Fix
Doc Text:
Prior to this update, if the /etc/resolv.conf file contained addresses that caused the connect system call to fail immediately, queries which triggered the search along the search path caused a segmentation fault to occur. This bug has been fixed, and segmentation faults no longer occur in the described scenario.
