CVE-2017-17790

Priority
Medium
Description
The lazy_initialize function in lib/resolv.rb in Ruby through 2.4.3 uses
Kernel#open, which might allow Command Injection attacks, as demonstrated
by a Resolv::Hosts::new argument beginning with a '|' character, a
different vulnerability than CVE-2017-17405. NOTE: situations with
untrusted input may be highly unlikely.
