EulerOS 2.0 SP1 : ruby (EulerOS-SA-2018-1029)
High Nessus Plugin ID 106404
SynopsisThe remote EulerOS host is missing a security update.
DescriptionAccording to the version of the ruby packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :
- 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.(CVE-2017-17790)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected ruby package.
