Ruby: Command injection

Ruby: Command injection A vulnerability has been found in Ruby which may allow for arbitrary command execution. ruby 2018-02-20 2018-02-20 641090 remote 2.2.9 2.2.9

Ruby is an interpreted object-oriented programming language. The elaborate standard library includes an HTTP server (“WEBRick”) and a class for XML parsing (“REXML”).

A command injection flaw was discovered in Net::FTP which impacts Ruby.

A remote attacker, by enticing a user to download and open a crafted file from a malicious FTP server, could execute arbitrary commands with the privileges of the process.

There is no known workaround at this time.

All Ruby users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-lang/ruby-2.2.9:2.2"
