Upgrade Debian:10
ruby2.5
to version 2.5.0-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream ruby2.5
package and not the ruby2.5
package as distributed by Debian
.
See How to fix?
for Debian:10
relevant fixed versions and status.
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.
